Terminal devices are usually used to store pictures, such as a smart phone with a camera function. After the user activates the camera function to take a picture, the generated picture is stored locally on the phone.

技术问题technical problem

由于终端设备的存储容量有限，故需要对终端设备存储的图片进行清理，在现有技术中，通常是根据某个单一的删除条件(如拍摄时间)对多个图片进行批量清理，而无法实现对真正需要清理的图片(如误拍图片)的针对性识别并清理，容易导致误删用户欲保留的图片。综上，现有技术中图片清理的针对性差。Due to the limited storage capacity of the terminal device, it is necessary to clean up the pictures stored in the terminal device. In the prior art, it is usually impossible to clean up multiple pictures in batches based on a single deletion condition (such as shooting time). The targeted identification and cleaning of pictures that really need to be cleaned up (such as pictures taken by mistake) can easily lead to accidental deletion of pictures that users want to keep. In summary, in the prior art, picture cleaning is poorly targeted.

In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details hindering the description of the present application.

为了说明本申请所述的技术方案，下面通过具体实施例来进行说明。In order to explain the technical solutions described in the present application, the following will be described with specific embodiments.

图1示出了本申请实施例提供的基于数据更新的图片清理方法的实现流程，详述如下：FIG. 1 shows the implementation process of the image cleaning method based on data update provided by an embodiment of the present application, which is detailed as follows:

在S101中，获取终端设备的当前剩余容量以及所述终端设备在预设时间段内的已用容量增长率，并根据所述当前剩余容量和所述已用容量增长率计算填充时长，所述填充时长指示所述当前剩余容量减少至零的时长。In S101, the current remaining capacity of the terminal device and the used capacity growth rate of the terminal device within a preset time period are obtained, and the filling time is calculated according to the current remaining capacity and the used capacity growth rate, the The filling time length indicates the time length during which the current remaining capacity is reduced to zero.

在本申请实施例中，为了减少图片清理的次数以节省资源，首先获取终端设备的当前剩余容量以及终端设备在预设时间段内的已用容量增长率，其中，当前剩余容量是指终端设备的内存可用量(当前剩余容量也可自定义设置)，已用容量增长率可为终端设备的内存已用量在预设时间段的增长率，计算公式如下：In this embodiment of the application, in order to reduce the number of times of picture cleaning to save resources, first obtain the current remaining capacity of the terminal device and the used capacity growth rate of the terminal device within a preset time period, where the current remaining capacity refers to the terminal device The amount of memory available (the current remaining capacity can also be customized), the used capacity growth rate can be the growth rate of the terminal device’s memory used in the preset time period, the calculation formula is as follows:

上述计算公式中，Raterise为已用容量增长率，Periodpreset为预设时间段，Capacityperiod-end为终端设备在预设时间段的末尾时间点的内存已用量，Capacityperiod-start为终端设备在预设时间段的起始时间点的内存已用量，已用容量增长率的数值可为正、负或零。预设时间段可根据实际应用场景进行设置，预设时间段的末尾时间点可为当前时间，当然也可为当前时间之前的任一时刻。举例来说，若预设时间段的末尾时间点为当前时间，预设时间段为7天，则获取终端设备当前的内存已用量，如4吉字节(GB)，并获取终端设备在7天前的内存已用量，如3吉字节，则可计算出已用容量增长率为(4-3)/7＝0.14，该已用容量增长率的单位为吉字节/天。值得一提的是，为了便于获取终端设备在不同时刻的内存已用量，可将内存已用量实时保存在终端设备的日志文件中，在计算已用容量增长率时，将预设时间段对应的时刻作为搜索条件，在日志文件中查找对应的内存已用量即可。In the above calculation formula, Raterise is the used capacity growth rate, Periodpreset is the preset time period, Capacityperiod-end is the memory used by the terminal device at the end of the preset time period, and Capacityperiod-start is the terminal device at the preset time The memory used at the start time point of the segment, and the value of the used capacity growth rate can be positive, negative or zero. The preset time period can be set according to actual application scenarios, and the end time point of the preset time period can be the current time, of course, can also be any time before the current time. For example, if the end time point of the preset time period is the current time and the preset time period is 7 days, the current memory usage of the terminal device is obtained, such as 4 gigabytes (GB), and the terminal device is The memory used a day ago, for example, 3 gigabytes, the used capacity growth rate can be calculated as (4-3)/7=0.14, and the unit of the used capacity growth rate is gigabytes/day. It is worth mentioning that, in order to facilitate the acquisition of the memory usage of the terminal device at different times, the memory usage can be saved in the log file of the terminal device in real time. When calculating the growth rate of the used capacity, the preset time period corresponds to Time is used as the search condition, just find the corresponding memory usage in the log file.

计算出的已用容量增长率可用于预测终端设备后续的内存已用量增长情况，故在本申请实施例中，根据得到的当前剩余容量和已用容量增长率计算填充时长，填充时长指预期的当前剩余容量减少至零所花费的时长，比如当前剩余容量为1吉字节，已用容量增长率为0.5吉字节/天，则可计算出填充时长为2天。值得一提的是，若已用容量增长率为负或为零，证明终端设备的内存已用量不存在增长趋势，则不计算填充时长，并且不进行图片清理。The calculated growth rate of the used capacity can be used to predict the subsequent increase in the amount of memory used by the terminal device. Therefore, in this embodiment of the application, the filling time is calculated according to the obtained current remaining capacity and the used capacity growth rate, and the filling time refers to the expected The time it takes for the current remaining capacity to decrease to zero. For example, if the current remaining capacity is 1 gigabyte and the used capacity growth rate is 0.5 gigabytes/day, the filling time can be calculated to be 2 days. It is worth mentioning that if the used capacity growth rate is negative or zero, which proves that there is no increasing trend in the memory usage of the terminal device, the filling time is not calculated and the picture cleaning is not performed.

可选地，获取预设时间段内的图片增长率，并根据当前剩余容量和图片增长率计算填充时长。在本申请实施例中，针对容量变化主要是由相册图片数量变化引起的场景，获取预设时间段内的图片增长率，并根据当前剩余容量和图片增长率计算填充时长，其中图片增长率相当于已用容量增长率的一种特殊形式。在根据图片增长率计算填充时长时，还获取终端设备上图片的平均容量，如1兆字节(MB)，该平均容量可自定义设置，也可在预设时间段的末尾时间点对终端设备上所有图片的容量进行均值计算得到平均容量。举例来说，在预设时间点的起始时间点，终端设备上相册图片的数量为100张，在预设时间点的末尾时间点，终端设备上相册图片的数量为200张，预设时间段为10天，则可计算出图片增长率为(200-100)/10＝10张/天，若当前剩余容量为100兆字节，平均容量为1兆字节，则可计算出填充时长为100/(10*1)＝10天。通过上述方法可单独针对相册图片的变化情况，从而控制是否进行图片清理，用户也可针对图片自定义设置当前剩余容量，以根据实际需求限制图片容量，提升了图片清理的针对性和准确性。Optionally, obtain the picture growth rate in a preset time period, and calculate the filling time according to the current remaining capacity and the picture growth rate. In the embodiment of this application, for the scenario where the capacity change is mainly caused by the change in the number of photos in the album, the image growth rate within a preset time period is obtained, and the filling time is calculated according to the current remaining capacity and the image growth rate, where the image growth rate is equivalent It is a special form of used capacity growth rate. When calculating the filling time according to the picture growth rate, the average capacity of the picture on the terminal device, such as 1 megabyte (MB), is also obtained. The average capacity can be customized, or the terminal can be set at the end of the preset time period. The average capacity of all pictures on the device is calculated to obtain the average capacity. For example, at the starting time of the preset time, the number of album pictures on the terminal device is 100, and at the end of the preset time, the number of album pictures on the terminal device is 200, and the preset time If the segment is 10 days, the image growth rate can be calculated as (200-100)/10=10 sheets/day. If the current remaining capacity is 100 megabytes and the average capacity is 1 megabyte, the filling time can be calculated It is 100/(10*1)=10 days. Through the above method, it is possible to control whether to clean up the pictures separately according to the changes of the pictures in the album. Users can also customize the current remaining capacity for pictures to limit the picture capacity according to actual needs, which improves the pertinence and accuracy of picture cleanup.

在S102中，若所述填充时长小于预设的时长阈值，则获取所有相册图片，并将满足预设条件的所述相册图片归入清理组，对所述清理组内的至少两个所述相册图片按照浏览次数进行排序。In S102, if the filling duration is less than a preset duration threshold, all album pictures are acquired, and the album pictures meeting the preset conditions are classified into a cleaning group, and at least two of the cleaning groups are Album pictures are sorted according to the number of views.

在得到填充时长后，将填充时长与预设的时长阈值(如1天)进行数值比较，若填充时长大于或等于时长阈值，则不进行图片清理；若填充时长小于时长阈值，则获取终端设备上所有相册图片，并将其中满足预设条件的相册图片归入清理组，然后对清理组内的至少两个相册图片按照浏览次数进行排序。其中，浏览次数是指相册图片被打开的次数，预设条件可根据实际应用场景进行设置，本申请实施例对此不做限定，比如预设条件可为相册图片的创建时间在预设时间点之前，还可为相册图片包含特殊的预设标识等。另外，本申请实施例中的清理组并不指定某种具体的存储格式，而是指示对满足预设条件的至少两个相册图片进行单独分类。After getting the filling duration, compare the filling duration with a preset duration threshold (such as 1 day). If the filling duration is greater than or equal to the duration threshold, no picture cleaning is performed; if the filling duration is less than the duration threshold, the terminal device is acquired Upload all album pictures, and group the album pictures that meet the preset conditions into the cleaning group, and then sort at least two album pictures in the cleaning group according to the number of views. Wherein, the number of views refers to the number of times the album picture is opened. The preset condition can be set according to actual application scenarios. The embodiment of this application does not limit this. For example, the preset condition may be the creation time of the album picture at a preset time point Previously, it was also possible to include special preset logos for album pictures. In addition, the cleaning group in the embodiment of the present application does not specify a specific storage format, but instructs to separately classify at least two album pictures that meet preset conditions.

在S103中，按照第一预设数量对排序后的至少两个所述相册图片进行选取，将选取出的所述相册图片确定为目标图片，并将所述清理组内除所述目标图片外的图片确定为待处理图片。In S103, at least two sorted album pictures are selected according to a first preset number, the selected album pictures are determined as target pictures, and the cleaning group except for the target pictures The picture of is determined to be a pending picture.

在对清理组内的至少两个相册图片进行排序时，可按照浏览次数从多到少的顺序进行排序，也可按照浏览次数从少到多的顺序进行排序，为了便于阐述本申请实施例的内容，后文以按照浏览次数从多到少的顺序进行排序进行说明。排序完成后，按照第一预设数量对排序后的至少两个相册图片进行图片选取，将选取出的相册图片确定为目标图片，并将清理组内除目标图片外的图片确定为待处理图片。其中，选取操作是从排序后的至少两个相册图片的起始开始。举例来说，清理组内排序后的相册图片依次为“图片1、图片2、图片3、图片4、图片5……”，第一预设数量为3个，则从图片1开始选取，选取出的“图片1、图片2、图片3”为目标图片，清理组内剩余的“图片4、图片5……”为待处理图片。When sorting at least two album pictures in the cleaning group, the pictures can be sorted in the order of the number of views from most to less, or they can be sorted in the order of the number of views from less to most, in order to facilitate the description of the embodiments of this application. The content will be described in the order of the most browsed times. After the sorting is completed, select at least two album pictures after sorting according to the first preset number, determine the selected album pictures as the target pictures, and determine the pictures in the cleaning group except the target pictures as the pictures to be processed . Wherein, the selection operation starts from the beginning of at least two album pictures after sorting. For example, the sorted album pictures in the cleaning group are "Picture 1, Picture 2, Picture 3, Picture 4, Picture 5...", and the first preset number is 3, then select from Picture 1, select The "Picture 1, Picture 2, Picture 3" that is output is the target picture, and the remaining "Picture 4, Picture 5..." in the cleaning group are the pictures to be processed.

在S104中，分别计算所述待处理图片与每个所述目标图片之间的子相似度，并根据所有所述子相似度计算所述待处理图片的综合相似度，对小于预设的相似度阈值的所述综合相似度所对应的所述待处理图片进行清理，所述综合相似度指示所述待处理图片与所有所述目标图片之间的总体相似程度。In S104, the sub-similarity between the picture to be processed and each target picture is calculated separately, and the comprehensive similarity of the picture to be processed is calculated according to all the sub-similarity. The picture to be processed corresponding to the comprehensive similarity of the degree threshold is cleaned up, and the comprehensive similarity indicates the overall similarity between the picture to be processed and all the target pictures.

由于目标图片的浏览次数较多，故目标图片与用户的浏览习惯较为贴合，故将目标图片作为图片清理的参照对象，具体地，对于一个待处理图片，首先分别计算出该待处理图片与每个目标图片之间的子相似度，本申请实施例对子相似度的计算方式不做限定，比如可通过对待处理图片的灰度直方图和目标图片的灰度直方图进行比较得到子相似度，可通过对待处理图片的彩色图像直方图和目标图片的彩色图像直方图进行比较得到子相似度，也可通过感知哈希算法计算子相似度。而由于目标图片的数量可能为两个或两个以上，不同的目标图片可能存在不同的风格，可能存在某个待处理图片与一个目标图片之间的子相似度较高，而与另一个目标图片之间的子相似度较低的情况，故根据得到的多个子相似度计算综合相似度，计算公式如下：Since the target picture has been viewed more frequently, the target picture is more closely related to the user’s browsing habits, so the target picture is taken as the reference object for picture cleaning. Specifically, for a picture to be processed, first calculate the picture to be processed and For the sub-similarity between each target picture, the embodiment of this application does not limit the calculation method of the sub-similarity. For example, the sub-similarity can be obtained by comparing the gray histogram of the image to be processed with the gray histogram of the target picture. The degree of sub-similarity can be obtained by comparing the color image histogram of the picture to be processed and the color image histogram of the target picture, and the sub-similarity degree can also be calculated by the perceptual hash algorithm. Since the number of target pictures may be two or more, different target pictures may have different styles, and there may be a high degree of sub-similarity between a picture to be processed and one target picture, but with another target picture. When the sub-similarity between pictures is low, the comprehensive similarity is calculated according to the obtained multiple sub-similarity. The calculation formula is as follows:

在上述计算公式中，Similarityphotos为综合相似度，Numberaim-photos为第一预设数量，Numberaim-photoi-views为第i个目标图片的浏览次数，Numberviews为预设的权重浏览次数(比如可设置为15次)，Similarityaim-photoi为计算出的待处理图片与第i个目标图片之间的子相似度。综合相似度即为待处理图片与所有目标图片之间的总体相似程度，在计算出综合相似度后，将综合相似度与预设的相似度阈值进行比较，若综合相似度大于或等于相似度阈值，则继续保留综合相似度对应的待处理图片；若综合相似度小于相似度阈值，则对该综合相似度对应的待处理图片进行清理。相似度阈值可以自定义设置，也可以根据清理组内的目标图片生成，比如设置权重浏览次数Numberviews为所有目标图片的总浏览次数，并设置某一个目标图片对应的子相似度为70％，设置其他的目标图片对应的子相似度为10％，从而将根据上述计算公式计算出的综合相似度确定为相似度阈值，当然，具体的参数可根据实际应用场景进行调整，并不限于上述例子。In the above calculation formula, Similarityphotos is the comprehensive similarity, Numberaim-photos is the first preset number, Numberaim-photoi-views is the number of views of the i-th target picture, Numberviews is the number of preset weighted views (for example, it can be set to 15 times), Similarityaim-photoi is the calculated sub-similarity between the picture to be processed and the i-th target picture. The comprehensive similarity is the overall similarity between the picture to be processed and all target pictures. After the comprehensive similarity is calculated, the comprehensive similarity is compared with the preset similarity threshold. If the comprehensive similarity is greater than or equal to the similarity If the comprehensive similarity is smaller than the similarity threshold, then the to-be-processed picture corresponding to the comprehensive similarity is cleaned up. The similarity threshold can be customized or generated based on the target pictures in the cleaning group. For example, set the weighted number of views to the total number of views of all target pictures, and set the sub-similarity corresponding to a target picture to 70%. The sub-similarity corresponding to other target pictures is 10%, so the comprehensive similarity calculated according to the above calculation formula is determined as the similarity threshold. Of course, the specific parameters can be adjusted according to actual application scenarios and are not limited to the above examples.

通过图1所示实施例可知，在本申请实施例中，通过终端设备的当前剩余容量以及已用容量增长率计算填充时长，若填充时长小于预设的时长阈值，则将终端设备中满足预设条件的相册图片归入清理组，对清理组内的至少两个相册图片进行排序，按照第一预设数量对排序后的至少两个相册图片进行选取，将选取出的相册图片确定为目标图片，并将清理组内除目标图片外的图片确定为待处理图片，分别计算待处理图片与每个目标图片之间的子相似度，并根据所有子相似度计算待处理图片的综合相似度，对小于预设的相似度阈值的综合相似度所对应的待处理图片进行清理，实现了对误拍图片的有效识别，提升了图片清理的针对性。It can be seen from the embodiment shown in FIG. 1 that, in the embodiment of the present application, the filling time is calculated based on the current remaining capacity of the terminal device and the used capacity growth rate. If the filling time is less than the preset duration threshold, the terminal device will meet the preset Set conditional album pictures into the cleanup group, sort at least two album pictures in the cleanup group, select at least two album pictures after sorting according to the first preset number, and determine the selected album pictures as the target Picture, and determine the pictures in the cleaning group except the target picture as the picture to be processed, calculate the sub-similarity between the picture to be processed and each target picture, and calculate the comprehensive similarity of the picture to be processed based on all the sub-similarity , To clean up the to-be-processed pictures corresponding to the comprehensive similarity that is less than the preset similarity threshold, which realizes the effective identification of mistaken pictures and improves the pertinence of picture cleaning.

图2所示，是在本申请实施例一的基础上，将对小于预设的相似度阈值的综合相似度所对应的待处理图片进行清理的过程进行细化后得到的一种方法。本申请实施例提供了基于数据更新的图片清理方法的实现流程图，如图2所示，该图片清理方法可以包括以下步骤：FIG. 2 shows a method obtained by refining the process of cleaning up the pictures to be processed corresponding to the comprehensive similarity that is less than the preset similarity threshold on the basis of the first embodiment of the present application. The embodiment of the present application provides an implementation flow chart of a picture cleaning method based on data update. As shown in FIG. 2, the picture cleaning method may include the following steps:

在S201中，筛选出小于所述相似度阈值的至少两个所述综合相似度所对应的至少两个所述待处理图片。In S201, at least two pictures to be processed corresponding to at least two comprehensive similarities that are smaller than the similarity threshold are filtered out.

在本申请实施例中，针对小于相似度阈值的综合相似度至少存在两个的情况，首先筛选出小于相似度阈值的至少两个综合相似度所对应的至少两个待处理图片，便于进行后续清理。In the embodiment of the present application, for the situation where there are at least two comprehensive similarities less than the similarity threshold, at least two pictures to be processed corresponding to the at least two comprehensive similarities less than the similarity threshold are first selected to facilitate subsequent follow-up Clean up.

在S202中，按照所述浏览次数对至少两个所述待处理图片进行排序，并按照第二预设数量对排序后的至少两个所述待处理图片进行选取。In S202, at least two pictures to be processed are sorted according to the number of times of browsing, and at least two pictures to be processed after sorting are selected according to a second preset number.

在筛选出至少两个待处理图片后，按照浏览次数对至少两个待处理图片进行排序，并按照第二预设数量对排序后的至少两个待处理图片进行选取，其中，第二预设数量可自定义设置，也可通过对终端设备的容量进行分析得到。值得一提的是，本步骤中的选取操作与S103中的选取操作不同，即优先从浏览次数最少的待处理图片开始选取，具体地，若是按照浏览次数从多到少的顺序对筛选出的至少两个待处理图片进行排序，则从排序后的最末尾的待处理图片开始执行选取。After screening at least two pictures to be processed, the at least two pictures to be processed are sorted according to the number of views, and the at least two pictures to be processed after sorting are selected according to the second preset number, where the second preset The quantity can be customized and can also be obtained by analyzing the capacity of the terminal device. It is worth mentioning that the selection operation in this step is different from the selection operation in S103, that is, the pictures to be processed with the least number of views are selected first. Specifically, if the selected images are selected in the order of the most viewed If at least two pictures to be processed are sorted, the selection is performed starting from the last picture to be processed after sorting.

在S203中，将选取出的所述待处理图片移动至待删除目录下，并基于所述待删除目录内的所述待处理图片输出删除提示。In S203, the selected picture to be processed is moved to a directory to be deleted, and a deletion prompt is output based on the picture to be processed in the directory to be deleted.

选取完成后，将选取出的待处理图片从其原目录移动至待删除目录下，并基于待删除目录内的待处理图片输出删除提示，用于指示用户对删除待处理图片的操作进行确认，防止误删，其中，可设置删除提示在被输出时直接显示待删除目录内的待处理图片。After the selection is completed, move the selected picture to be processed from its original directory to the directory to be deleted, and output a delete prompt based on the picture to be processed in the directory to be deleted, which is used to instruct the user to confirm the operation of deleting the picture to be processed. To prevent accidental deletion, the delete prompt can be set to directly display the pending pictures in the to-be-deleted directory when output.

在S204中，若接收到关于所述删除提示的确认结果，则删除所述待删除目录下的所述待处理图片。In S204, if a confirmation result regarding the deletion prompt is received, the to-be-processed picture in the to-be-deleted directory is deleted.

在本申请实施例中，输出的删除提示还包括确认和否认两个可选结果。若接收到用户关于删除提示的确认结果，则对待删除目录下的待处理图片执行删除操作，完成图片清理工作。In the embodiment of the present application, the output deletion prompt also includes two optional results of confirmation and denial. If the user's confirmation result about the deletion prompt is received, the deletion operation is performed on the pending pictures in the directory to be deleted, and the picture cleaning is completed.

在S205中，若接收到关于所述删除提示的否认结果，则将所述待删除目录下的所述待处理图片移动至所述待处理图片的原目录。In S205, if a denial result regarding the deletion prompt is received, the to-be-processed picture in the to-be-deleted directory is moved to the original directory of the to-be-processed picture.

若接收到关于删除提示的否认结果，则将待删除目录下的待处理图片移动至待处理图片的原目录。值得一提的是，由于待删除目录下可能存在至少两个待处理图片，则可基于每个待处理图片都生成一个删除提示，或者直接基于待删除目录下的所有待处理图片生成一个删除提示，并设置该删除提示包含每个待处理图片对应的两个可选结果。If a denial result regarding the deletion prompt is received, the to-be-processed picture in the to-be-deleted directory is moved to the original directory of the to-be-processed picture. It is worth mentioning that since there may be at least two pictures to be processed in the directory to be deleted, a deletion prompt can be generated based on each picture to be processed, or a deletion prompt can be generated directly based on all the pictures to be processed in the directory to be deleted , And set the delete prompt to include two optional results corresponding to each picture to be processed.

可选地，若在输出删除提示后的删除时间段内并未接收到关于删除提示的确认结果或否认结果，则将待删除目录下的待处理图片上传至云空间，并对该待处理图片进行删除。在本申请实施例中，可预先设置删除时间段，如10分钟，若在输出删除提示后的删除时间段内并未接收到用户关于删除提示的回应结果(确认结果或否认结果)，则将待删除目录下的待处理图片上传至云空间，并对该待处理图片进行删除，通过上述方法一方面增加了终端设备的内存可用量，另一方面在未经用户允许误删待处理图片的情况下，用户也可通过云空间访问待处理图片，提升了图片清理的适用性。Optionally, if the confirmation result or denial result of the deletion prompt is not received within the deletion time period after the deletion prompt is output, the picture to be processed in the directory to be deleted is uploaded to the cloud space, and the picture to be processed is To delete. In the embodiment of this application, the deletion time period can be preset, such as 10 minutes. If the user's response to the deletion prompt (confirmation result or denial result) is not received within the deletion time period after the deletion prompt is output, the The pictures to be processed in the directory to be deleted are uploaded to the cloud space, and the pictures to be processed are deleted. The above method increases the available memory of the terminal device on the one hand, and on the other hand deletes the pictures to be processed by mistake without the user’s permission. In this case, users can also access to-be-processed pictures through the cloud space, which improves the applicability of picture cleaning.

通过图2所示实施例可知，在本申请实施例中，筛选出小于相似度阈值的至少两个综合相似度所对应的至少两个待处理图片，按照浏览次数对至少两个待处理图片进行排序，并按照第二预设数量对排序后的至少两个待处理图片进行选取，将选取出的待处理图片移动至待删除目录下，并基于待删除目录内的待处理图片输出删除提示，若接收到关于删除提示的确认结果，则删除待删除目录下的待处理图片；若接收到关于删除提示的否认结果，则将待删除目录下的待处理图片移动至待处理图片的原目录。本申请实施例根据浏览次数对至少两个待处理图片进行排序，提升了对综合相似度小于相似度阈值的待处理图片进行清理的有序性。It can be seen from the embodiment shown in FIG. 2 that, in the embodiment of the present application, at least two pictures to be processed corresponding to at least two comprehensive similarities less than the similarity threshold are selected, and the at least two pictures to be processed are performed according to the number of views. Sort, and select at least two pictures to be processed after sorting according to the second preset number, move the selected pictures to be processed to the directory to be deleted, and output a deletion prompt based on the pictures to be processed in the directory to be deleted, If a confirmation result about the deletion prompt is received, the to-be-processed picture in the directory to be deleted is deleted; if a denial result about the deletion prompt is received, the to-be-processed picture in the to-be-deleted directory is moved to the original directory of the to-be-processed picture. In the embodiment of the present application, at least two pictures to be processed are sorted according to the number of browsing times, which improves the order in cleaning the pictures to be processed whose comprehensive similarity is less than the similarity threshold.

图3所示，是在本申请实施例二的基础上，并在预设条件为相册图片与预设标识存在对应关系，预设标识为至少两个图片标识中的一个的基础上，对按照第二预设数量对排序后的至少两个所述待处理图片进行选取之前的过程进行扩展后得到的一种方法。本申请实施例提供了基于数据更新的图片清理方法的实现流程图，如图3所示，该图片清理方法可以包括以下步骤：As shown in Figure 3, it is based on the second embodiment of the present application, and on the basis of the preset condition that the album picture has a corresponding relationship with the preset logo, and the preset logo is one of at least two image logos, The second preset number is a method obtained by expanding the process before selecting at least two of the pictures to be processed after sorting. The embodiment of the present application provides an implementation flow chart of a picture cleaning method based on data update. As shown in FIG. 3, the picture cleaning method may include the following steps:

在S301中，获取记录的已删除图片数量，并从中识别出与所述预设标识对应的图片数量，将与所述预设标识对应的图片数量与所述已删除图片数量之间的比值确定为所述清理组对应的删除占比。In S301, the number of recorded deleted pictures is obtained, the number of pictures corresponding to the preset identifier is identified therefrom, and the ratio between the number of pictures corresponding to the preset identifier and the number of deleted pictures is determined Is the percentage of deletions corresponding to the cleaning group.

在本申请实施例中，设置终端设备中存储的每个相册图片都对应一个图片标识，该图片标识是在将该相册图片存入终端设备时由用户手动设置或根据特定的分析算法自动生成，举例来说，图片标识可为人像、风景或动态图等。在进行图片清理时，将各个图片标识依次作为预设标识，并将相册图片与预设标识存在对应关系作为预设条件，即依次生成至少两个清理组，每个清理组都与一个图片标识对应。为了便于阐述本申请实施例的内容，后文以根据某个预设标识对对应的清理组内的图片进行图片清理进行说明。除此之外，在本申请实施例中，设置终端设备包括记录机制，即终端设备对已删除图片数量以及每个已删除图片对应的图片标识进行记录(已删除图片可以是自动删除或用户手动删除)，在本步骤中，从记录的已删除图片数量中识别出与预设标识对应的图片数量，获取预设标识对应的图片数量与已删除图片数量之间的比值，并将该比值确定为根据预设标识生成的清理组对应的删除占比，比如已删除图片数量为100张，其中包含50张风景图，而当前的预设标识为风景，则确定出删除占比为50％。In the embodiment of the application, each album picture stored in the terminal device is set to correspond to a picture identifier, which is manually set by the user or automatically generated according to a specific analysis algorithm when the album picture is stored in the terminal device. For example, the picture logo can be a portrait, landscape, or dynamic picture. When cleaning up pictures, each picture ID is used as the preset ID in turn, and the corresponding relationship between the album picture and the preset ID is used as the preset condition, that is, at least two cleaning groups are generated in sequence, and each cleaning group is associated with a picture ID correspond. In order to facilitate the elaboration of the content of the embodiments of the present application, the following description will be described by performing picture cleanup on the pictures in the corresponding cleanup group according to a certain preset identifier. In addition, in the embodiment of this application, setting the terminal device includes a recording mechanism, that is, the terminal device records the number of deleted pictures and the picture identifier corresponding to each deleted picture (the deleted pictures can be deleted automatically or manually by the user). Delete). In this step, the number of pictures corresponding to the preset logo is identified from the number of deleted pictures recorded, the ratio between the number of pictures corresponding to the preset logo and the number of deleted pictures is obtained, and the ratio is determined In order to delete the proportion corresponding to the cleaning group generated according to the preset mark, for example, the number of deleted pictures is 100, including 50 landscape pictures, and the current preset mark is a landscape, the deletion proportion is determined to be 50%.

在S302中，根据所述当前剩余容量计算出待删除容量，并根据所述删除占比和所述待删除容量计算所述预设标识对应的删除容量。In S302, the capacity to be deleted is calculated according to the current remaining capacity, and the deletion capacity corresponding to the preset identifier is calculated according to the percentage of deletion and the capacity to be deleted.

根据已获取的当前剩余容量计算待删除容量，一种计算方式是获取预设的安全剩余容量，并将安全剩余容量与当前剩余容量之间的差值确定为待删除容量，比如安全剩余容量为1吉字节，当前剩余容量为0.5吉字节，则待删除容量为0.5吉字节。然后，对删除占比和待删除容量进行乘积运算，得到预设标识对应的删除容量，比如删除占比为50％，待删除容量为0.5吉字节，则预设标识对应的删除容量为0.25吉字节。Calculate the capacity to be deleted according to the current remaining capacity that has been obtained. One calculation method is to obtain the preset safe remaining capacity and determine the difference between the safe remaining capacity and the current remaining capacity as the capacity to be deleted. For example, the safe remaining capacity is 1 gigabyte, the current remaining capacity is 0.5 gigabytes, and the capacity to be deleted is 0.5 gigabytes. Then, multiply the percentage of deletions and the capacity to be deleted to obtain the deletion capacity corresponding to the preset logo. For example, if the percentage of deletion is 50% and the capacity to be deleted is 0.5 gigabytes, the deletion capacity corresponding to the preset logo is 0.25 Gigabytes.

在S303中，计算所述清理组内筛选出的所有所述待处理图片的平均容量，并根据所述平均容量和所述预设标识对应的删除容量计算所述第二预设数量。In S303, the average capacity of all the pictures to be processed filtered out in the cleaning group is calculated, and the second preset number is calculated according to the average capacity and the deletion capacity corresponding to the preset identifier.

对于预设标识对应的清理组，首先筛选出小于相似度阈值的至少两个综合相似度所对应的至少两个待处理图片，再计算筛选出的所有待处理图片的平均容量，并将预设标识对应的删除容量除以平均容量，得到第二预设数量，在后续步骤中根据第二预设数量对排序后的至少两个待处理图片进行选取，比如删除容量为100兆字节，平均容量为5兆字节，则可计算出第二预设数量为20张。值得一提的是，若清理组内根据相似度阈值筛选出的待处理图片的数量少于第二预设数量，则可按照综合相似度从小到大的顺序，对综合相似度大于或等于相似度阈值的待处理图片进行继续选取，直到选取出的待处理图片的数量达到第二预设数量为止。For the cleaning group corresponding to the preset identifier, at least two pictures to be processed corresponding to at least two comprehensive similarities less than the similarity threshold are first screened out, and then the average capacity of all the pictures to be screened out is calculated, and the preset The deletion capacity corresponding to the identifier is divided by the average capacity to obtain the second preset number. In the subsequent step, at least two pictures to be processed after sorting are selected according to the second preset number. For example, the deletion capacity is 100 megabytes, and the average If the capacity is 5 megabytes, the second preset number can be calculated as 20 sheets. It is worth mentioning that if the number of pictures to be processed filtered according to the similarity threshold in the cleaning group is less than the second preset number, the overall similarity can be in the order of ascending, and the overall similarity is greater than or equal to similarity. The selection of pictures to be processed with a degree threshold is continued until the number of selected pictures to be processed reaches the second preset number.

通过图3所示实施例可知，在本申请实施例中，获取记录的已删除图片数量，从中识别出与预设标识对应的图片数量，将与预设标识对应的图片数量与已删除图片数量之间的比值确定为清理组对应的删除占比，并根据当前剩余容量计算出待删除容量，根据删除占比和待删除容量计算预设标识对应的删除容量，计算清理组内筛选出的所有待处理图片的平均容量，并根据平均容量和预设标识对应的删除容量计算第二预设数量。本申请实施例根据预设标识计算删除占比，从而计算根据该预设标识得到的清理组对应的第二预设数量，使得图片清理过程更贴近用户对不同类型图片的删除习惯，提升了图片清理的适用性和用户体验。It can be seen from the embodiment shown in FIG. 3 that, in the embodiment of the present application, the number of recorded deleted pictures is obtained, the number of pictures corresponding to the preset identifier is identified therefrom, and the number of pictures corresponding to the preset identifier is compared with the number of deleted pictures The ratio between is determined as the proportion of deletions corresponding to the cleaning group, and the capacity to be deleted is calculated according to the current remaining capacity, the deletion capacity corresponding to the preset flag is calculated according to the proportion of deletions and the capacity to be deleted, and all the filtered out in the cleaning group are calculated The average capacity of the pictures to be processed is calculated, and the second preset quantity is calculated according to the average capacity and the deleted capacity corresponding to the preset identifier. The embodiment of the present application calculates the percentage of deletions based on the preset identification, thereby calculating the second preset number corresponding to the cleaning group obtained according to the preset identification, so that the image cleaning process is closer to the user's deletion habits of different types of images, and the image is improved Applicability and user experience of cleanup.
