背景技术Background technique
目前许多视频通话产品都已支持在视频通话的过程中添加美颜、滤镜或背景替换等特效功能，这些特效功能深受用户的欢迎。在支持这些特效功能的视频通话产品中，当用户想添加特效时，需要先调起特效菜单，再点击选择，操作步骤比较繁琐。尤其在来电场景中，用户需要同时处理接听电话和调整特效菜单两种任务，操作很不方便。故亟需一种添加特效的快捷操作。At present, many video calling products already support adding special effects such as beauty, filters or background replacement during video calls, which are very popular among users. In the video call products that support these special effects, when users want to add special effects, they need to call up the special effects menu first, and then click to select, and the operation steps are rather cumbersome. Especially in the incoming call scenario, the user needs to deal with the two tasks of answering the call and adjusting the special effect menu at the same time, which is very inconvenient to operate. Therefore, a shortcut operation for adding special effects is urgently needed.
现有技术中的视频通话产品，通常在来电界面中显示特效图标，用户点击特效图标就能展开特效菜单或美颜调节条。当用户需要应用特效时，需要先点击特效图标，展开特效编辑菜单，再点击选择特效缩略图或在菜单内滑动调节美颜级别。在用户交互过程中，用户需要至少两次点击才能开启指定的特效，交互过程繁琐，整个流程耗时较长，并且图标的点击区域比较小，不方便快捷操作。故无法满足在来电状态下快速达到开启特效的目的。In the video call products in the prior art, special effects icons are usually displayed on the incoming call interface, and the user can click on the special effects icons to expand the special effects menu or the beauty adjustment bar. When users need to apply special effects, they need to click the special effect icon to expand the special effect editing menu, and then click to select the special effect thumbnail or slide in the menu to adjust the beauty level. In the user interaction process, the user needs at least two clicks to activate the specified special effect, the interaction process is cumbersome, the entire process takes a long time, and the click area of the icon is relatively small, which is inconvenient to operate quickly. Therefore, it cannot meet the purpose of quickly enabling special effects in the state of incoming calls.

当D＞D min且V＞V min时，执行步骤Step180。 When D>D min and V>V min , step Step180 is executed.
以从屏幕侧边向中心右滑为例。判断手指在屏幕上的坐标位移|Xs-Xe|与预设的最小距离D min的大小关系，以及滑动速度Vx与预设的最小速度Vmin的大小关系； Take the example of swiping right from the side of the screen to the center. Determine the relationship between the coordinate displacement |Xs-Xe| of the finger on the screen and the preset minimum distance Dmin , and the relationship between the sliding speed Vx and the preset minimum speed Vmin;
当|Xs-Xe|＞D min且V x＞V min时，则判断为有效滑动。 When |Xs-Xe|> Dmin and Vx > Vmin , it is determined that the sliding is valid.
其核心思路为：实时捕捉和记录用户手指在屏幕中二维坐标轴的坐标位置(x,y)的运动轨迹和速度(如图4a至图4b所示)。The core idea is to capture and record the movement trajectory and speed of the user's finger on the screen at the coordinate position (x, y) of the two-dimensional coordinate axis in real time (as shown in Figure 4a to Figure 4b).

需要注意的是，在安卓手机上该滑动手势动作可能是***默认的Home键(起始键)功能，因此在该场景下要注意***级手势监听捕捉。It should be noted that on Android phones, the swipe gesture action may be the default Home button (start button) function of the system, so in this scenario, attention should be paid to system-level gesture monitoring and capture.
同理可得，若手指从屏幕顶端向下滑，则坐标位移为|Ys-Ye|，滑动速度为V y，余下步骤代入上文所述的条件和步骤即可。 Similarly, if the finger slides down from the top of the screen, the coordinate displacement is |Ys-Ye|, the sliding speed is V y , and the remaining steps can be substituted into the conditions and steps described above.
本实施例的视频特效添加方法，预先设定最小距离D min和最小速度V min作为判断用户的手指是否有效滑动的标准，通过计算手指在屏幕上的坐标位移D和滑动速度V，来判断用户的手指是否真的在进行手势操作，避免发生错误相应用户在屏幕上的误触碰而错误添加特效素材的问题。 In the video special effect adding method of this embodiment, the minimum distance D min and the minimum speed V min are preset as the criteria for judging whether the user's finger slides effectively, and the user is judged by calculating the coordinate displacement D and sliding speed V of the finger on the screen.

如图5a至图5c所示，用户的手指在执行角滑动手势时，其角向心移动动作识别触发条件为起点O必须在图5b的方框形状的起点区域内，50为参考值，可根据实际需要或者屏幕灵敏度适当调整起点区域大小。As shown in Fig. 5a to Fig. 5c, when the user's finger performs the corner sliding gesture, the trigger condition for the recognition of its angular centripetal movement action is that the starting point O must be within the starting point area of the box shape in Fig. 5b, and 50 is a reference value, which can be determined according to Adjust the size of the starting point area according to actual needs or screen sensitivity.
角向心滑动动作识别是基于图4a至图4c所示的边滑动手势的判断条件做适当优化后得到的判断规则，以图5c中点A为终点为例，A坐标设为(X(A)，Y(A))，起点是(X(O),Y(O))。判断规则如下：Angular centripetal sliding action recognition is a judgment rule obtained after appropriate optimization based on the judgment conditions of the side sliding gesture shown in Figure 4a to Figure 4c.

③直线AO的斜率k范围在(0.268，3.73)，即对应移动偏移的角度在15°到75°之间，如图4c中OAB三角形区域所示。(三角区范围可根据实际需求适当调整)。③ The slope k of the straight line AO is in the range of (0.268, 3.73), that is, the angle corresponding to the movement offset is between 15° and 75°, as shown in the OAB triangle area in Figure 4c. (The scope of the triangle area can be appropriately adjusted according to actual needs).
滑动区域识别(即等腰直角三角形区域识别)：基于手指滑动的滑动终点进行如下处理：以图5c中点A为例，设A为用户滑动的滑动终点，过点A做一条斜率为-1的直线，则该直线与坐标轴的所围成的三角形区域即为滑动区域，因为该直线斜率为-1，因此与坐标轴的内角均为45°，如图5c所示，等腰直角三角形，为实现图中三角形区域的背景替换做好准备。Sliding area recognition (ie, isosceles right-angled triangle area recognition): Based on the sliding end point of finger sliding, the following processing is performed: Take point A in Figure 5c as an example, set A as the sliding end point of the user's sliding, and make a line through point A with a slope of -1 , then the triangle area enclosed by the line and the coordinate axis is the sliding area, because the slope of the line is -1, so the interior angle with the coordinate axis is 45°, as shown in Figure 5c, the isosceles right triangle , in preparation for the background replacement of the triangle area in the figure.
图5c仅例举了终端设备的一个角的情形，其他三个角处的判断规则可以根据图5c所例举的情形推断而得，最终得出判断规则为0.268<|k|<3.73或0.268<|k -1|<3.73。 Figure 5c only exemplifies the situation of one corner of the terminal device, the judgment rules at the other three corners can be inferred from the situation exemplified in Figure 5c, and the final judgment rule is 0.268<|k|<3.73 or 0.268 <|k -1 |<3.73.

具体来说，在本实施例所公开的方法中，以*** android(谷歌安卓)标准camera(摄像头)API2.0引擎为例，可使用其他camera引擎输出连续的图像帧数据，帧数据格式可为YUV-NV21或者RGB等通用格式。先对原始图像使用双线性插值算法进行下采样，例如将原始1920 x 1080分辨率图像下采样为320 x 180分辨率的图像，从而得到下采样图像；在对下采样后的下采样图像进行人像分割处理，此处人像分割使用的深度学习模型在本发明实施例中不做限制，可采用CNN、FCN/FCN+/UNet等等常见的模型。人像分割处理后会输出具有人物的轮廓(Mask)的数据，其本质是一帧图像，如图9所示，但需注意该轮廓的分辨率暂为320x180，在此处通过处理低分辨率的轮廓，大幅度降低人像分割的计算复杂度和功耗开销。将输出的轮廓使用双线性插值算法进行上采样至原始图像的分辨率(本实施例中为1920x1080)，由于是对黑白图像进行上采样，因此其上采样插值的图像损失率能够降低到最低。基于上述的轮廓的数据，将人像从原始图像中“抠出来”，得到第一图层，再与经过背景的特效素材替换的第二图层在GPU上进行图层叠加渲染，最终得到背景替换后的效果图。Specifically, in the method disclosed in this embodiment, taking the *** android (Google Android) standard camera API 2.0 engine as an example, other camera engines can be used to output continuous image frame data, and the frame data format can be Common formats such as YUV-NV21 or RGB. First, downsample the original image using a bilinear interpolation algorithm, for example, downsample the original 1920 x 1080 resolution image to a 320 x 180 resolution image to obtain a downsampled image; For portrait segmentation processing, the deep learning model used for portrait segmentation here is not limited in the embodiments of the present invention, and common models such as CNN, FCN/FCN+/UNet, etc. may be used. After the portrait segmentation processing, the data with the outline (Mask) of the person will be output, which is essentially a frame of image, as shown in Figure 9, but it should be noted that the resolution of the outline is temporarily 320x180. contour, which greatly reduces the computational complexity and power consumption of portrait segmentation. Use the bilinear interpolation algorithm to upsample the output contour to the resolution of the original image (1920x1080 in this embodiment). Since the black-and-white image is upsampled, the image loss rate of the upsampling interpolation can be reduced to a minimum. . Based on the above-mentioned outline data, the portrait is "keyed out" from the original image to obtain the first layer, which is then layered and rendered on the GPU with the second layer replaced by the special effect material of the background, and finally the background replacement is obtained. After effects.
本实施例的视频特效添加方法，采用双线性插值法逐帧对原始图像下采样，使分辨率等比例减少，且降低算力损耗，然后做人像分割，输出人像的轮廓，后再使用双线性插值法将轮廓上采样为原始图像的分辨率。从而大幅度降低人像分割在移动终端设备上的功耗和处理时延，满足30FPS的视频通话的帧率要求。该方法在做人像分割之前，对原始图像进行下采样处理，从而大幅度降低人像分割的计算和功耗开销，从而允许需要大计算量的深度学习人像分割模型算法能够运行在算力和功耗受限的移动终端上，满足视频播放的帧率要求。In the video special effect adding method of this embodiment, the bilinear interpolation method is used to downsample the original image frame by frame, so that the resolution is proportionally reduced, and the computing power consumption is reduced, and then the portrait is segmented, the outline of the portrait is output, and then the double Linear interpolation upsamples the contour to the resolution of the original image. Thereby, the power consumption and processing delay of portrait segmentation on mobile terminal devices are greatly reduced, and the frame rate requirements of 30FPS video calls are met. This method down-samples the original image before doing portrait segmentation, thereby greatly reducing the computational and power consumption overhead of portrait segmentation, thus allowing the deep learning portrait segmentation model algorithm that requires a large amount of computation to run in computing power and power consumption. On limited mobile terminals, it meets the frame rate requirements for video playback.
在本实施例的视频特效添加方法中，根据第一区域的区域面积或第一区域占屏幕的屏幕占比，选择特效素材的添加等级。In the video special effect adding method of this embodiment, the adding level of the special effect material is selected according to the area of the first area or the screen ratio of the first area on the screen.
本实施例的视频特效添加方法，在添加特效素材的过程中，用户可以自行选择添加特效素材的量，体现在操作应用中就是可以根据用户的手指滑过屏幕的区域大小来 选择特效素材的添加等级，这样的操作方法能够满足用户更多、更复杂的特效添加需求。In the video special effect adding method of this embodiment, in the process of adding special effect materials, the user can choose the amount of special effect materials to be added. In the operation application, the user can select the addition of special effect materials according to the size of the area where the user's finger slides across the screen. This method of operation can meet the needs of users for more and more complex special effects additions.
在本实施例的视频特效添加方法中，手势动作每划过10％，特效素材的添加等级对应提升一级。In the video special effect adding method of the present embodiment, the addition level of the special effect material is correspondingly increased by one level for every 10% of the gesture action.
本实施例的视频特效添加方法，能够给用户提供更加平滑的视频特效添加体验。The method for adding video special effects in this embodiment can provide users with a smoother experience of adding video special effects.
在实际应用中，可以上文图4a至图4c所描述的边滑动手势沿屏幕的横向/纵向的捕捉方法触发美颜类算法，以其滑动区域占整个屏幕的比例作为美颜级别。以十级美颜为例：比如从左侧或者顶部开始滑，滑动区域占比为10％时，开启一级美颜，全部滑到右侧时开启十级美颜，以此类推。In practical applications, the beautification algorithm can be triggered by the capture method of the side sliding gesture described in Figures 4a to 4c along the horizontal/vertical direction of the screen, and the ratio of the sliding area to the entire screen is used as the beauty level. Take the ten-level beauty as an example: for example, start sliding from the left or the top, when the sliding area accounts for 10%, the first-level beauty is turned on, when all the slides to the right, the ten-level beauty is turned on, and so on.
由于美颜为级别实现类的特效，因此建议使用边滑动手势捕捉触发方法，但如有业务需求或产品设计等因素，亦可使用角滑动手势捕捉方法触发，两者实现思路类似。Since beauty is a level-implemented special effect, it is recommended to use the edge swipe gesture capture trigger method, but if there are factors such as business requirements or product design, the corner swipe gesture capture method can also be used to trigger the trigger. The two implementation ideas are similar.
在本实施例的视频特效添加方法中，当第一区域的屏幕占比大于50％且所述手势动作的滑动终点的终点坐标信息不再变化时，将屏幕的整个背景进行特效素材替换。In the video special effect adding method of this embodiment, when the screen ratio of the first area is greater than 50% and the coordinate information of the end point of the sliding end point of the gesture action no longer changes, the entire background of the screen is replaced with special effect material.
本实施例的视频特效添加方法，由于用户在手指滑动大半的情况下往往就代表着有全部替换背景的需求，故采用本优选实施方案的方法能够便于用户操作，增强用户体验。In the method for adding video special effects in this embodiment, since the user often needs to replace all backgrounds when the user slides most of their fingers, the method of this preferred embodiment can facilitate user operations and enhance user experience.

若滑动速度小于第二速度，则不执行步骤Step200；其中，第一速度大于第二速度。If the sliding speed is less than the second speed, step Step 200 is not executed; wherein, the first speed is greater than the second speed.
本实施例的视频特效添加方法，预设两个用于判断滑动速度的判断条件，结合用户滑动速度判断本次滑动是否生效，如果滑动速度很快，滑动速度大于第一速度时，可以认为用户需要对整个背景进行替换，则开启背景的完整替换或虚化，滑动速度小于第二速度时，可以认为用户并没有执行滑动手势，也就不用启动应用特效素材的步骤。In the method for adding video special effects in this embodiment, two judgment conditions for judging the sliding speed are preset, and whether the current sliding is effective is judged in combination with the sliding speed of the user. If the sliding speed is fast and the sliding speed is greater than the first speed, it can be considered that the user If the entire background needs to be replaced, the complete replacement or blurring of the background is enabled. When the sliding speed is less than the second speed, it can be considered that the user has not performed the sliding gesture, and the step of applying the special effect material does not need to be started.

若滑动方向为远离手指在屏幕上的滑动起点的正向时，执行步骤Step240：添加新的特效素材；If the sliding direction is the forward direction away from the sliding starting point of the finger on the screen, step 240 is performed: adding a new special effect material;
若滑动方向为朝向手指在屏幕上的滑动起点的反向时，执行步骤Step250：恢复上一个特效素材。If the sliding direction is the opposite direction toward the starting point of sliding the finger on the screen, step 250 is performed: the last special effect material is restored.
如图11所示，用户的手指在执行手势动作的时候，可以通过多次滑动对特效素材进行切换，即在前文所述的规则基础上，再次滑动手指，就能更换为下一个特效素材。As shown in Figure 11, when the user's finger performs a gesture action, the special effect material can be switched by sliding multiple times.
本实施例的视频特效添加方法，通过对滑动方向的识别，给用户提供回溯的操作，可以将屏幕的背景替换/虚化进行取消，比如手指向左滑，开启背景替换/虚化；手指再 向左滑，换另一个背景素材；手指向右滑(即反向操作)，恢复上一个背景素材/真实背景。这样用户可以在多个特效素材中自由地选择更喜欢的特效素材，而不会为滑过喜欢的特效素材而担心，增强用户体验。The method for adding video special effects in this embodiment provides the user with a retrospective operation by recognizing the sliding direction, and can cancel the background replacement/blur of the screen, for example, slide your finger to the left to enable background replacement/blur; Swipe left to change to another background material; swipe right (that is, reverse operation) to restore the previous background material/real background. In this way, the user can freely select the preferred special effect material from among multiple special effect materials, without worrying about sliding over the favorite special effect material, which enhances the user experience.
