For convenience of understanding, the embodiment of the present invention may select one user terminal from the plurality of user terminals shown in fig. 1 as the target user terminal, for example, the user terminal 3000a shown in fig. 1 may be used as the target user terminal. Wherein, the target user terminal may include: the intelligent terminal comprises an intelligent terminal with a picture editing function, such as a smart phone, a tablet computer, a desktop computer and an intelligent television. Each terminal can edit pictures in a client corresponding to an application including a picture editing function, where the pictures referred to in the picture editing can be understood as network pictures downloaded from a network, pictures stored in a social application, pictures stored in a user album application, or pictures taken by a camera (e.g., a rear camera) in the terminal.

Referring to fig. 2, fig. 2 is a flow chart illustrating a picture editing method according to an embodiment of the present disclosure. The picture editing method shown in fig. 2 includes the steps of:

s101: and acquiring a picture to be edited, and extracting at least one picture characteristic color from the picture to be edited.

Referring to fig. 3, fig. 3 is a schematic view of a scene for editing a picture according to an embodiment of the present invention. As shown in fig. 3, the scenario takes a terminal 3000a in the embodiment corresponding to fig. 1 as an example, where applications such as application a, application B, and application C may be displayed to a user based on the terminal, and at this time, the user may access the application by clicking any application among the application a, application B, and application C, so that in a process of accessing any application among the application a, application B, and application C, a picture editing operation on any picture among the application a, application B, and application C is triggered. Optionally, in the process that the user triggers a picture editing operation on any picture in any application of the application a, the application B, and the application C, a picture that is designated as a picture to be edited in any application of the application a, the application B, and the application C that the user attempts to acquire may be used to perform the picture editing operation.

In some feasible embodiments, after the terminal obtains the picture to be edited, the terminal may analyze the picture information to be edited in a preset feature space, for example, analyze a color vector of each pixel point of the picture in an RGB color space, to obtain a feature vector of each pixel point in the picture to be edited. A preset clustering algorithm is utilized to randomly generate a plurality of clustering centers in the pixel points of the picture to be edited, and for convenience of expression, in this embodiment, a k-means algorithm and 16 clustering centers are taken as an example for description. The terminal can calculate the distance from each pixel point to each clustering center and classify the pixel points into the category represented by the clustering center closest to the pixel point. The terminal can calculate the arithmetic mean of the pixel points in each sample category in turn, and mark the pixel point closest to the arithmetic mean in each category as a new clustering center. Judging whether the clustering centers in all the categories are changed or not, if so, clustering all the pixel points by using the new clustering center again until all the clustering centers are not changed or the distance between the new clustering center and the old clustering center is less than a set threshold value, terminating the algorithm to obtain 16 final clustering centers, and extracting the color represented by the pixel points of the clustering centers at the moment as the picture characteristic color of the picture to be edited. The distance from each pixel point to each cluster center can be calculated by formulae such as Euclidean distance, Manhattan distance, Chebyshev distance, cosine distance and the like, and can be specifically determined according to an actual application scene without limitation.

In some feasible implementation modes, due to the fact that the size of the picture to be edited is too large, the clustering process is too slow, the resolution of the picture to be edited can be reduced, at the moment, the terminal can extract the characteristic color of the picture after the picture is down-sampled to the preset size, the clustering speed can be guaranteed while the characteristic color extraction result is not influenced, and the efficiency of a clustering algorithm is improved.

S102: and generating a picture paster set according to the at least one picture characteristic color, and outputting the picture paster set to a picture editing user interface for a user to select.

In some possible implementations, referring to fig. 4, fig. 4 is an interface schematic diagram of a picture editing method provided in an embodiment of the present invention. When a user accesses the application A to obtain a picture to be edited, performs picture characteristic color extraction on the picture to be edited, and generates the picture sticker set, the terminal can generate a request for requesting the application A to display the generated picture sticker set, so that the picture sticker set is generated on a picture editing user interface for the user to select. The terminal can determine the target sticker style and the target sticker style selected by the user by collecting the click operation of the user on the sticker collection area 200 c.

In some possible embodiments, the set of picture stickers includes a plurality of alternative picture stickers, and the alternative picture stickers include at least one sticker pattern color and at least one picture sticker pattern. That is, the picture sticker sets may include alternative picture stickers formed by applying picture characteristic colors in the same picture sticker style, or may include alternative picture stickers formed by applying picture characteristic colors in a plurality of picture sticker styles. The terminal may determine the target sticker style selected by the user by collecting the user's click operation on the portion of the sticker style in the sticker collection area 200 c. For example, the terminal may capture a user click operation on the portion of the decal color in the decal collection area 200c, as shown in the solid line portion in fig. 4, to determine the target decal color selected by the user. While the user switches the click operation on the sticker-like color portion, the color of the picture sticker in the sticker collection area 200c can be changed accordingly, as shown by the dotted line portion in fig. 4.

In some possible embodiments, after extracting the characteristic color of the picture to be edited based on a picture editing operation triggered by a user, since the extracted characteristic color of the picture may be too close to the color of the picture to be edited and is not suitable for being used as the sticker color of the picture sticker, the terminal may configure the sticker color parameter in the request for generating the picture sticker set sent by the application a, so that the sticker color also includes some commonly used sticker colors as the preset sticker colors. Specifically, the terminal may obtain a request for generating a picture sticker set sent by the application a, determine a request for generating a sticker pattern color carried in the request for generating a picture sticker set, determine a preset sticker pattern color called by the request for generating a picture sticker set according to the request for generating a sticker pattern color, and display the preset sticker pattern color in the sticker set area 200 c. That is, the sticker pattern color may include the picture characteristic color, or may include a preset sticker pattern color. The terminal can determine the target sticker style and the target sticker style selected by the user by collecting the click operation of the user on the sticker collection area 200 c.

S103: and determining the target sticker color and the target sticker style selected by the user based on the picture editing user interface, and applying the target sticker color selection to the target sticker style to generate a target sticker.

In some possible implementations, when the user selects the destination sticker paper pattern and the target sticker paper pattern by clicking the sticker collection area, and generates the target sticker, a display interface of the terminal is as shown in fig. 5, where fig. 5 is another interface diagram of the picture editing method provided by the embodiment of the present invention.

In some possible embodiments, after selecting the target sticker style and the target sticker style, if the target sticker style is a sticker style that can add text, the text editing region 400b may be output to a picture editing user interface displayed by the terminal for editing by the user. Wherein, the user can select the color of the sticker text and input the sticker text by clicking the text editing area 400 b. The terminal can detect the user operation command to determine the color of the sticker text selected by the user and/or the sticker text input by the user, so as to generate the corresponding sticker text, and display the corresponding target sticker in the sticker adjustment area 400 c.

In some possible embodiments, the terminal may obtain the color of the sticker text selected by the user by collecting the user's operation on the text editing area 400 b. The method comprises the steps of pasting the character color and the picture characteristic color of the paper and presetting the optional character color. The terminal may determine the user-selected text color of the sticker by collecting the user's clicking operations on the text color portion of the sticker in the text editing area 400b, as shown by the solid line portion in fig. 5. While the user switches the click operation for selecting the character color of the sticker, the terminal can change the character color of the picture sticker accordingly, as shown by the dotted line portion in fig. 5. Or automatically generating the character color according to the brightness of the label paper pattern color selected by the user. For example, when the lightness of the sticker sample color is greater than or equal to a preset value, the sticker sample color is brighter, and the text color is automatically determined to be black; when the lightness of the paste paper sample color is smaller than the preset value, the paste paper sample color is darker, and the character color is automatically determined to be white.

S104: and adding the target paster to the picture to be edited to generate a target picture.

As shown in fig. 5, in some possible embodiments, after the terminal generates the target sticker, the user may perform operations of adjusting the target sticker, such as zooming in, zooming out, mirroring and rotating, on the display interface. The user operation instruction is obtained based on the picture editing user interface, if the user needs to adjust the target sticker in the picture editing process, the target sticker to be adjusted can be selected by clicking the sticker adjustment area 400c in the picture display area 400a to be edited, and operations such as amplification, reduction, mirroring or rotation of the target sticker are performed in the corresponding area. The terminal may generate a request for requesting application a to adjust the target sticker after detecting a user-triggered operation to adjust the target sticker. After the user confirms that the target sticker is adjusted, a request for confirming the generation of the target picture can be sent to the application A by clicking confirmation, and therefore the target picture is generated.

The following describes in detail the extraction of the characteristic color of the picture in the picture editing method provided by the present application with reference to fig. 6. Referring to fig. 6, fig. 6 is a schematic flow chart of extracting a characteristic color of a picture according to an embodiment of the present application. The method for extracting the characteristic color of the picture as shown in FIG. 6 comprises the following steps:

s201: at least two pixel points with the color saturation greater than or equal to a preset saturation threshold are obtained from the picture to be edited and serve as initial clustering centers.

In some feasible embodiments, after the terminal acquires the picture to be edited, analyzing the information of the picture to be edited in a preset feature space, for example, analyzing the color vector of each pixel point of the picture in the RGB color space, to obtain the feature vector of each pixel point in the picture to be edited. A preset clustering algorithm is utilized to randomly generate a plurality of clustering centers in the pixel points of the picture to be edited, and for convenience of expression, in this embodiment, a k-means algorithm and 16 clustering centers are taken as an example for description.

Since the characteristic color of the picture extracted at last by the method of randomly generating the cluster center has a certain randomness, in some feasible embodiments, the method of initializing the cluster center can be utilized to ensure that the color extracted each time is stable.

In some feasible embodiments, the terminal can analyze the pixel point information of the picture to be edited through different color spaces, so as to optimize the selection of the initial clustering center. For example, because it is difficult to numerically obtain the vividness of the color of a pixel point in the RGB color space, HSV (Hue, Saturation, brightness) color space may be used to analyze the pixel points of the picture to be edited, sort the Saturation of the pixel points of the picture to be edited, select the Saturation of the 16 th pixel point as the Saturation threshold, extract the pixel points whose Saturation is greater than or equal to the threshold as the initial clustering center, and thereby use the pixel points with the most vivid color in the picture to be edited as the initial clustering center.

In some feasible embodiments, the terminal may also set a saturation threshold according to practical applications, and select 16 pixel points of which the saturation is greater than or equal to the threshold in the picture to be edited as initial clustering centers, so as to use the pixel points with the most vivid color in the picture to be edited as the initial clustering centers.

In some feasible implementation manners, besides analyzing color characteristics such as hue, saturation and lightness of each pixel point of the picture to be edited, the terminal can also add information such as spatial position of the pixel points to jointly construct a feature space, and increase the feature vector dimension of the pixel points, so that the clustering result is more accurate.

S202: and clustering the pixel points in the picture to be edited according to the initial clustering center to obtain the color of the pixel points in the clustering center, and taking the color of the pixel points in the clustering center as an initial characteristic color.

In some feasible embodiments, the terminal may calculate the distance from each pixel point in the picture to be edited to each cluster center, and classify the pixel point into the category represented by the cluster center closest to the pixel point. And sequentially calculating the arithmetic mean of the pixel points in each sample category, and marking the pixel point closest to the arithmetic mean in each category as a new clustering center. The terminal can judge whether the clustering centers in all the categories are changed, if the clustering centers are changed, the new clustering centers are used for clustering all the pixel points again until all the clustering centers are not changed or the distance between the new clustering centers and the old clustering centers is smaller than a set threshold value, the algorithm is terminated, 16 final clustering centers are obtained, and the color represented by the pixel points of the clustering centers at the moment is extracted to be used as the picture characteristic color of the picture to be edited. The distance from each pixel point to each clustering center calculated by the terminal can be calculated by formulae such as Euclidean distance, Manhattan distance, Chebyshev distance, cosine distance and the like, and can be specifically determined according to an actual application scene without limitation.

S203: at least one weighting parameter for each of the initial characteristic colors is determined, and a weighting coefficient for each weighting parameter for each of the initial characteristic colors is determined.

In some possible embodiments, after obtaining the initial characteristic color, the terminal may obtain a more desirable characteristic color by weighting the initial characteristic color, for example, obtain a characteristic color with a larger color block area or a characteristic color with a higher brightness in the picture to be edited. Illustratively, the hue weight coefficient may be set to 2, the saturation weight coefficient to 1, the lightness weight coefficient to 0.5, and the area weight coefficient to 5000.

S204: and calculating the color weight of each initial characteristic color according to the weighting parameter of each initial characteristic color and the weighting coefficient of each weighting parameter, and sequencing the initial characteristic colors according to the order of the color weight of each initial characteristic color from high to low.

In some possible embodiments, after obtaining the weighting parameters and the weighting coefficients, the terminal may calculate the color weight of each initial characteristic color according to a preset weighting formula. For example, the color weights of the initial characteristic colors are calculated according to formula one, and the 16 initial characteristic colors are sorted according to the order of the obtained color weights from high to low.

Wherein, the first formula is: color weight is area weight coefficient area ratio + saturation weight coefficient saturation + lightness weight coefficient lightness + hue weight coefficient hue.

S205: and calculating the color distance between the initial characteristic colors, and removing the initial characteristic color with smaller color weight from the two initial characteristic colors with the color distance smaller than a preset color distance threshold value to obtain at least one initial characteristic color as the picture characteristic color of the picture to be edited.

In some possible embodiments, after the terminal sorts the 16 initial characteristic colors from high to low according to the color weights, in order to make the picture characteristic colors representative and more comprehensive, the initial characteristic colors may be screened and similar colors may be removed, so as to obtain the picture characteristic colors.

In some possible embodiments, the terminal may calculate color distances between 16 initial feature colors, select the first-ranked initial feature color as a first picture feature color, remove the initial feature color whose color distance from the first-ranked initial feature color is smaller than a threshold value from the next 15 initial feature colors, use the second-ranked initial feature color as a second picture feature color, delete the initial feature color whose color distance from the second-ranked initial feature color is smaller than the threshold value from the next initial feature colors, and so on until a preset number of picture feature colors are obtained, or filter all initial feature colors to obtain the picture feature colors.

The color processing module 502 is configured to extract at least one characteristic color from the picture to be edited.

In some feasible embodiments, after the picture to be edited is obtained by the picture obtaining module 501, the color processing module 502 is utilized to analyze the information of the picture to be edited in a preset feature space, for example, the color vector of each pixel point of the picture in the RGB color space is analyzed, so as to obtain the feature vector of each pixel point in the picture to be edited. A preset clustering algorithm is utilized to randomly generate a plurality of clustering centers in the pixel points of the picture to be edited, and for convenience of expression, in this embodiment, a k-means algorithm and 16 clustering centers are taken as an example for description. And calculating the distance from each pixel point to each clustering center, and classifying the pixel points into the category represented by the clustering center closest to the pixel points.

The distance from each pixel point to each cluster center can be calculated by formulae such as Euclidean distance, Manhattan distance, Chebyshev distance, cosine distance and the like, and can be specifically determined according to an actual application scene without limitation.

Since the characteristic color of the image extracted last by the method of randomly generating the cluster center has a certain randomness, in some possible embodiments, the color processing module 502 further includes an initial clustering unit 5021 for initializing the cluster center to ensure that the color extracted each time is stable.

In some feasible embodiments, the pixel point information of the picture to be edited can be analyzed through different color spaces, so that the selection of the initial clustering center is optimized. For example, because it is difficult to numerically obtain the vividness of the color of a pixel point in the RGB color space, HSV (Hue, Saturation, brightness) color space may be used to analyze the pixel points of the picture to be edited, sort the Saturation of the pixel points of the picture to be edited, select the Saturation of the 16 th pixel point as the Saturation threshold, extract the pixel points whose Saturation is greater than or equal to the threshold as the initial clustering center, and thereby use the pixel points with the most vivid color in the picture to be edited as the initial clustering center.

In some possible embodiments, after obtaining the initial characteristic colors, the initial characteristic colors may be weighted by the color sorting unit 5022 to obtain more desirable characteristic colors, such as characteristic colors with larger color patch areas or characteristic colors with higher lightness in the picture to be edited. Illustratively, the hue weight coefficient may be set to 2, the saturation weight coefficient to 1, the lightness weight coefficient to 0.5, and the area weight coefficient to 5000.

In some possible embodiments, after obtaining the weighting parameters and the weighting coefficients, the color ranking unit 5022 may calculate the color weights of the initial characteristic colors according to a preset weighting formula. For example, the color weights of the initial characteristic colors are calculated according to the second formula, and the 16 initial characteristic colors are sorted according to the order of the obtained color weights from high to low.

Wherein, the formula two is: color weight is area weight coefficient area ratio + saturation weight coefficient saturation + lightness weight coefficient lightness + hue weight coefficient hue.
