The method for generating the brush pattern according to the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Fig. 1 is a schematic flowchart of a method for generating a brush pattern according to an embodiment of the present application. As shown in fig. 1, the method for generating a brush pattern according to the embodiment of the present application includes the following steps 102 to 106.

And 102, acquiring the color and the shape of the target object in the target picture as the target color and the target shape of the brush.

The target picture can be any picture selected by the user based on the requirement of the user, for example, an image of a landscape, a person or an article on the picture, wherein the landscape, the person or the article is mapped or supported by the emotion of the user. The target object may be a certain area or the whole area on the picture, e.g. a corresponding person or item.

Multiple colors may be included on the picture, and the color of the target object may be one or more, some or all of the multiple colors on the picture, as determined based on the user's color selection. Likewise, a plurality of closed-shape regions may be included on the picture, and the shape of the target object may be one or more corresponding shapes, partially or wholly, of the plurality of closed-shape regions on the picture, determined based on the region selection by the user.

Optionally, in one embodiment, the color of the target object includes a first color and a second color. Acquiring the color of a target object in a target picture as the target color of the brush, wherein the acquiring comprises the following steps: acquiring the color with the largest target object area in the target picture as the first color; and acquiring the color with an included angle smaller than or equal to a preset angle with the first color in the color ring as the second color.

The first color and the second color are different colors, and the second color may be one or more.

Referring to fig. 2A, as shown in (a) of fig. 2A, a target picture P is any one picture selected by a user, and then, the target picture P is uniformly divided into a plurality of pixel blocks of a predetermined size, as shown in (b) of fig. 2A. The colors in each pixel block are extracted and sorted according to the area ratio, for example, as shown in (C) in fig. 2A, the color with the largest specific area is a, followed by color B, color C, and the like. The color a with the largest specific area in the target picture P is extracted as the first color.

The preset angle may be in a range of 100 degrees to 120 degrees when the second color is extracted. The second color and the first color extracted in the way are adjacent colors, the hue of the colors cannot be greatly different from each other, and the color matching color is more attractive.

Referring to fig. 2B, colors included at an angle less than or equal to a preset angle θ with respect to the first color a in the color wheel include a color C and a color B, where the extracted color C and color B are the second color.

Optionally, obtaining the shape of the target object in the target picture includes: converting the target picture into a black and white mode; determining a plurality of closed shape areas in a target picture in a black and white mode; and acquiring the maximum closed shape area in the plurality of closed shape areas to obtain the shape of the target object in the target picture.

Referring to fig. 3, for the target picture P selected by the user, the black-and-white mode is converted to obtain a black-and-white picture P'. Only black and white colors, and no gray-scale color, exist in the black-and-white picture P'. At least one closed shape region can be obtained from the black-and-white picture P', and if a plurality of closed shape regions exist, the largest closed shape region is extracted, that is, the shape of the closed shape region in the target picture, for example, the shape corresponding to the region S shown in fig. 3, is obtained.

Selecting the one of the closed shape regions having the largest specific area as the target region can make it easier for the user to imagine the picture he or she selects.

In other embodiments, the target closed shape region may also have a user-customized shape, such as a closed region in the shape of a flower, love, or the like.

And after the color and the shape of the target object in the target picture are obtained, taking the obtained color and the obtained shape of the target object in the target picture as the target color and the target shape of the brush.

Optionally, the obtaining the color and the shape of the target object in the target picture as the target color and the target shape of the brush includes: determining a first point and a second point with the largest distance in the shape of the target object; setting the first color to correspond to the first point, and setting the second color to correspond to the second point; generating a gradient color based on the first color and the second color; and covering the gradient color into the shape of the target object based on the first point and the second point to obtain the target color and the target shape of the brush.

If the target closed shape region is an irregular figure, two points corresponding to the maximum vertical distance in the region are determined, such as the point a and the point b in the region S of fig. 4. Then, the color a with the largest area ratio is extracted and associated with the point a, and one of the extracted second colors is associated with the point b.

As described above, the extracted second colors may be one or more, and when there are a plurality of second colors, one of the second colors may be selected to be set corresponding to the point b according to a user's requirement for generating a gradient color. For example, when the user wishes to generate a two-color gradation color, a third color having the largest area ratio may be selected from the plurality of second colors to generate a two-color gradation with the first color. When the user wishes to generate a three-color gradation color, a fourth color whose area ratio is the largest and a second largest third color may be selected from the plurality of second colors to generate a three-color gradation with the first color.

Accordingly, when one of the extracted second colors corresponds to the point b, a color having the smallest area ratio among the second colors may be set to correspond to the point b.

In the embodiment of fig. 4, a bicolor gradient color D is generated based on color a and color B, where color a and color B are linearly gradient. By setting the color a corresponding to the point a in the area S and the color B corresponding to the point B in the area S, the bicolor gradation color D can be overlaid in the closed-shape area S, resulting in the target image M. The color of the target image M is a two-color gradation color D, and the shape of the target image M is the outer closed contour shape of the closed shape region S.

In this way, the generated gradient color can be arranged in the corresponding closed shape area as far as possible, and a better visual effect can be displayed for a user.

Optionally, generating a gradient color based on the first color and the second color includes: determining a third color with the largest specific area in the second colors; generating a bi-color gradient color based on the first color and the third color.

Or determining a fourth color with the largest specific area and a third color with the second largest specific area in the second colors; generating a tri-color gradient color based on the first color, the fourth color, and the third color. The three-color gradient color may be generated according to the order of the three colors in terms of the area ratio, for example, the three-color gradient color may be generated according to the order of the first color, the fourth color, and the third color.

In other embodiments, the target color may also be presented in other varying ways.

In the above-described embodiment, the acquisition of the color and the acquisition of the shape of the target object within the target picture may be performed separately, respectively.

In another embodiment, optionally, acquiring the color and shape of the target object in the target picture includes: acquiring a target picture containing a first number of color types; determining a plurality of regions of the target picture containing colors of a second number of color categories; acquiring a target area with the largest adjacent color contrast in the plurality of areas, wherein the second number is smaller than the first number; forming a shape of a target object in the target area in a preset closed shape.

For example, a target picture obtained by a user at least includes pictures of 5 colors, a region including 3 colors in the target picture is identified, and 3 adjacent color contrasts in each region are calculated. And extracting the area with the maximum contrast, and performing area division on the maximum area in any closed shape desired by the user to obtain a target closed shape area containing the 3 colors.

That is, in this embodiment, the shape of the target object is determined on the region containing the target color based on the target color and the preset closed shape.

Accordingly, in step 102, acquiring the color and shape of the target object in the target picture as the target color and target shape of the brush comprises: determining the color proportion of each color in the shape of the target object according to the main tone of the target picture; determining a first point and a second point with the largest distance in the shape of the target object; setting a first color with the largest color ratio in the colors to correspond to the first point, and setting a second color with the smallest color ratio in the colors to correspond to the second point; carrying out gradient processing on each color according to the color proportion to generate a gradient color; and covering the gradient color into the shape of the target object based on the first point and the second point to obtain the target color and the target shape of the brush.

The target color and the target shape of the brush obtained according to the steps of the above embodiment may be used to generate a brush pattern, for example, a software module recognizable by a computer may be used to generate a corresponding brush pattern by a user operating the brush.

Optionally, step 106 displays a pattern of the target shape and the target color according to the input trajectory of the first input, including: determining a target position according to the length of the first input track and a preset interval value; displaying a pattern of the target shape and target color at the target location.

As shown in fig. 6, when the user moves the brush on the screen to form a target input track T, the position of the pattern with the shape and color corresponding to the brush is determined according to the length of the current input track and the preset interval, that is, one brush M is set at each preset distance until the user stops moving the brush, and the input track is ended. And continuously and repeatedly setting a brush pattern M by the brush along the input track to obtain the dynamic wallpaper W corresponding to the continuous brush pattern.

The preset interval value may be determined by setting one brush pattern per predetermined length of movement of the brush, for example, setting the brush pattern 1 time per 2 pixels of movement, and if the input trajectory is 300 pixels, sequentially setting 150 times the target image according to the corresponding position.

Optionally, step 106 displays a pattern of the target shape and the target color according to the input trajectory of the first input, including: determining the number of the displayed target shapes and target color patterns according to the length of the first input track and the length of the screen corresponding to the input track; the number of patterns is displayed uniformly along the input trajectory.

In this embodiment, the number of brush patterns displayed is determined in conjunction with the input track length of the user with the screen length as a reference. Assuming that the screen length is X, the input track length drawn by the user using the brush is Y, Y is divided by X, and multiplied by a preset value n, for example, 100-. The number of brush patterns displayed on the screen is obtained.

For example, when Y is 2800 and X is 2400, the number of times the brush is repeatedly displayed is about 163, and a dynamic wallpaper corresponding to a continuous brush pattern is obtained.

And after the plurality of brush patterns are generated and the corresponding dynamic wallpaper is obtained, the background color of the dynamic wallpaper comprising the plurality of brush patterns can be set based on the color selected by the user.

Optionally, the method further includes: and setting the background of the dynamic wallpaper corresponding to the screen in the area except the brush pattern in the dynamic wallpaper.

The set background can be filled according to a recommended color customized by a system or one color freely selected by a user, and the filled area is the part except the dynamic wallpaper in the area displayed on the screen.

As shown in fig. 7, the user may select a favorite color in the color ring of the system to match with the generated dynamic wallpaper W, so as to obtain a dynamic wallpaper W' with a background.
