At present, the color noise swirl image generation has wide application prospect in the fields of art and computer graphics, and can be used for simulating a Sanskyscraper style image. However, the generation of such a style image in the related art requires a neural network to perform style migration, and requires a large amount of computing resources and computing time, resulting in low image generation efficiency. In order to solve the technical problem, the present invention proposes an image generating method, and fig. 2 is a schematic flow chart of the image generating method according to an embodiment of the present invention, as shown in fig. 2, the method includes the following steps:

step S202, an initial image and a color noise image are acquired.

In this step, the initial image obtained is an image in which a color noise swirl effect needs to be generated. Fig. 3 is a color noise diagram in an image generating method according to an alternative embodiment of the present invention, where, as shown in fig. 3, the color noise image is a color scattered-dot image with noise texture, and may be used to generate a color noise effect in a color noise vortex effect, where the noise texture refers to a pattern generated by a noise function, and includes random, irregular details and variations therein. The generation of the noise texture may be based on a noise function, which may include various types of noise, such as Perlin noise, simplex noise, and the like. By adjusting parameters of the noise function, the appearance, density, color and other attributes of the noise texture can be controlled, so that the noise texture is suitable for different application requirements. Specifically, different color noise images can be selected and generated according to the requirements of users, because the number and the dispersion degree of the color scattering points in the color noise images are different, the finally generated color noise vortex effect images are different.

In step S204, a movement track is generated for each of the plurality of pixels of the color noise image, wherein the movement track is used for simulating the vortex effect.

In this step, the movement tracks corresponding to the plurality of pixel points in the color noise image may be used to simulate the vortex effect. All pixel points can be selected for movement, and part of the pixel points can be selected for movement. The length and the moving direction of the moving track of the pixel point can influence the vortex effect in the finally generated color noise vortex effect. Specifically, since the swirl effect may be constituted by a plurality of curves around a certain point, a curve generation function may be employed to generate a movement locus corresponding to a pixel point. The method can also generate a plurality of vortexes in the image according to the requirements of the user, and the movement tracks of the corresponding pixel points are different and can be curves respectively surrounding a plurality of centers.

Step S206, based on the movement track of each of the plurality of pixels of the color noise image, the color of the plurality of pixels of the color noise image is adjusted to obtain a vortex image.

In this step, the color of the pixel point in the color noise image is adjusted based on the movement track of each of the plurality of pixel points in the color noise image, so that the movement track of the pixel point can be displayed on the color noise image, thereby forming a swirl effect. Specifically, the color of the pixel point on the corresponding moving track can be adjusted according to the color of the pixel point, so that a track stub is formed. Therefore, the moving track of the pixel points in the color noise image after moving on the image can be simulated, and the visual effect of vortex is presented.

Step S208, generating a target image according to the initial image and the swirl image, wherein the target image is a color noise swirl effect diagram of the initial image.

In this step, fig. 4 is a view showing a color noise swirl effect diagram of a target image, that is, an initial image, which is generated by superimposing the initial image and the swirl image as shown in fig. 4 in the image generation method according to the alternative embodiment of the present invention. The color of the pixel point in the swirl image can be overlapped on the pixel point corresponding to the initial image, and a color noise swirl effect diagram is obtained. The brightness of different pixel points in the target image can be adjusted, so that the vortex presents a deep and shallow effect. The brightness of the pixel points of the vortex area is improved, so that the vortex area is more prominent. The color noise swirl effect graph can be used for simulating a Sanskyscraper night style graph. Since the Van-Gao-Ye style is representative of the Van-Gao art style of the painter, the bright stars and night sky in the work "Star-Ye" are presented in a swirl-like stroke. In the related art, to generate such a image of the style of the Sanskyscraper, it is necessary to perform style learning using a neural network and then transfer the style to another image. This requires a significant amount of computing resources and computing time. According to the invention, the color noise image is adopted to generate the vortex image, and then the color noise vortex effect image, namely the image in the Sanskyscraper night style, can be obtained according to the combination of the vortex image and the initial image, so that the generation efficiency of the image can be improved.

Through the steps, the purpose of reducing the calculation resources and calculation time occupied in the image generation process is achieved, so that the technical effect of improving the image generation efficiency is achieved, and the technical problem that a large amount of calculation time is required for style learning by adopting a neural network to generate the image with the color swirl effect in the related art, so that the image generation efficiency is low is solved.

As an alternative embodiment, generating movement tracks for a plurality of pixels of a color noise image, respectively, includes: determining a swirl region in the color noise image; determining a vortex center of the vortex region; and generating a corresponding movement track for the pixel points in the vortex area based on the vortex center.

Alternatively, generating the movement trajectory may first determine a swirl region in the color noise image, wherein the swirl region is used to determine the position of the swirl. In general, the swirl area has a circular or elliptic curve shape, a swirl center exists in the swirl, surrounding gas or liquid is influenced to rotate around the swirl center, the area where the rotating part is located is the swirl area, that is, pixels in the swirl area in the color noise image all move around the swirl center of the corresponding swirl area, and the generated movement track is a curve curved towards the swirl center of the corresponding swirl area. Specifically, a plurality of circular or elliptical areas can be randomly generated in the color noise image to serve as vortex areas, the vortex areas can be set according to the requirements of users, and the number and the size of the vortex areas can be determined according to the requirements of the users. The number, the size and the shape of the vortex areas can influence the finally generated color noise vortex effect diagram, so that the vortex areas are determined according to the requirements of users, the color noise vortex effect diagram can be generated in a personalized mode, and the requirements of the users are better met. The cobble image may also be selected as a division standard of the vortex area, and fig. 5 is a gray scale chart of cobbles in the image generating method according to an alternative embodiment of the present invention, as shown in fig. 5, it may be seen that the cobble image is composed of a plurality of irregular circles or ellipses, where. Each cobble (i.e. the lighter areas in fig. 5) may act as a swirl area. The gray level image of the cobble image and the color noise image can be overlapped, and then a vortex area is divided in the color noise image. Specifically, the brightness values of a plurality of pixel points in the cobble image can be obtained, as shown in fig. 5, the color of the cobble part is brighter, the background color is darker, the brightness values of the pixel points in the cobble image are superimposed on the corresponding pixel points in the color noise image, and the position of the vortex area can be presented in the color noise image. The cobble image is adopted to determine the vortex area in the color noise image more quickly, so that the image generation efficiency is improved. In addition, the vortex centers of the vortex areas can be randomly determined, each vortex area has a corresponding vortex center, and the vortex centers are used for limiting the orientation of the movement tracks corresponding to the pixels in the vortex areas. Because the peripheral gas or liquid in one vortex region rotates around the center of the vortex, the corresponding movement track of the pixel points in the vortex region is a curve bent towards the corresponding vortex center. The movement track can be generated for the pixel points outside the vortex area, and the movement track can be linear movement or curve movement. And generating a moving track for the pixel points outside the vortex area, so that the finally generated image frame is richer.

As an alternative embodiment, generating a corresponding movement track for the pixel points in the vortex area based on the vortex center includes: generating a movement function corresponding to the vortex region based on the vortex center; randomly generating a time value for the pixel points in the swirling area; substituting a time value corresponding to the pixel point in the vortex area into a movement function to obtain a movement result corresponding to the pixel point in the vortex area; and determining a movement track corresponding to the pixel points in the vortex area according to the movement result corresponding to the pixel points in the vortex area, wherein the bending direction of the movement track corresponding to the pixel points in the vortex area faces towards the vortex center.

Alternatively, the movement track may be generated by first generating a movement function corresponding to the vortex region from the vortex center, and since the curve in the vortex should be curved toward the vortex center, the corresponding movement function needs to be generated from the position of the vortex center in the vortex region. Wherein the movement function is related to a time value, and the larger the time value is, the longer the obtained movement track is. The movement function is used for representing the time-varying relation of the movement parameter, wherein the movement parameter can comprise various types of angles and distances for the movement of the pixel points in the vortex area or coordinates of the pixel points, when the movement parameter is the angles and the movement distances for the rotation of the pixel points, the angles and the movement distances are changed along with the time variation, the movement result of the movement function is that the positions of the pixel points after the movement are determined according to the angles and the distances, and in particular, the angles and the movement distances for the rotation of the pixel points in the vortex area can be described through a polar coordinate equation so as to determine the movement track. When the movement parameter is the coordinate of the pixel point, the abscissa and the ordinate of the pixel point are changed along with the change of time, the movement result of the movement function is to determine the position of the pixel point after movement according to the coordinate, specifically, the x-axis coordinate and the y-axis coordinate of the pixel point in the vortex area can be described by a parameter equation to be changed along with the change of time, and then the movement track is determined. For example, a coordinate system may be established on the color noise image, and the center of the vortex in each vortex region is set as the origin, and then the coordinates of the center of the vortex are (0, 0). Assuming that the coordinates of the pixel point are (0, r), the angular velocity of the pixel point in the vortex region is ω. The movement function of the pixel point may be set as x (t) =r×cos (ωt), y (t) =r×sin (ωt), where t is time, and x (t) and y (t) represent coordinates of the pixel point on the x axis and the y axis during movement, respectively, and based on the parameter function, the movement track generated by the pixel point is a circular arc with the center of the vortex as a center of the circle. The time value can be randomly generated for the pixel points in the vortex area, so that movement tracks with different lengths can be formed, and the finally generated vortex effect is more natural. Substituting the time value of the corresponding pixel point in the vortex area into the corresponding movement function to obtain the movement result corresponding to the pixel point, and obtaining the movement track corresponding to the pixel point according to the movement result. Specifically, when the time value randomly generated for a certain pixel point is 5 seconds, the position to which the pixel point moves in 1 second, 2 seconds, 3 seconds, 4 seconds and 5 seconds can be obtained, and the movement track corresponding to the pixel point can be determined according to the positions.

As an alternative embodiment, adjusting colors of a plurality of pixels of a color noise image based on movement trajectories of the plurality of pixels of the color noise image to obtain a vortex image includes: selecting a pixel point meeting a preset condition from a plurality of pixel points of the color noise image as a moving pixel point; determining the pixel points forming the moving track corresponding to the moving pixel points as track pixel points; and adjusting the color of the corresponding track pixel point according to the color of the moving pixel point to obtain a vortex image.

Alternatively, a pixel satisfying a preset condition is selected from a plurality of pixels of the color noise image as the moving pixel, where the preset condition may be that the color value is a certain color or a certain colors. Since there are a plurality of colors in the color noise image, a part of the pixels may be selected as the moving pixels, for example, pixels of black, blue, and green exist in the color noise image, and the preset condition may be set to be blue or green, and then the pixels of blue and green are selected as the moving pixels. And taking the pixel point through which the moving track corresponding to the moving pixel point passes as a track pixel point, and then adjusting the color of the corresponding track pixel point according to the color of the moving pixel point to obtain the vortex image. Specifically, the color of the track pixel point can be adjusted to the color of the corresponding moving pixel point, so that the track pixel point becomes a curve, and a plurality of curves can form a vortex. When the moving tracks corresponding to the plurality of moving pixel points pass through the same pixel point, namely one track pixel point corresponds to the plurality of moving pixel points. The color of the trace pixel may be selected to be set to the color of any one of the corresponding moving pixels. By changing the color of the trace pixel points, the image shows the vortex effect.

As an alternative embodiment, generating the target image from the initial image and the vortex image includes: selecting a target area matched with the size of the initial image from the vortex image; and overlapping the colors of the plurality of pixel points in the target area to the colors of the corresponding pixel points in the initial image to obtain the target image.

Alternatively, since the swirl image may be larger than the initial image, the same area as the initial image may be selected in the swirl image first as the color noise swirl image of the initial image. And then, the colors of the plurality of pixel points in the target area are overlapped on the corresponding pixel points in the initial image, so that the target image can be obtained. The color of the pixel point in the target area can be multiplied by a coefficient and then superimposed on the pixel point of the initial image, and the finally generated target image can meet the requirement of a user by continuously adjusting the coefficient.

As an alternative embodiment, a Web graphic library is used to generate a target image from the initial image and the swirl image.

Alternatively, a Web graphic library may be employed to enable the generation of a target image from the initial image and the swirl image. Wherein a Web graphic library is a collection of tools for creating and processing graphics in Web page development. It includes various graphic processing functions such as drawing graphics, adding animation effects, processing images, etc., which can help developers quickly create attractive and interactive web page graphics. Through the Web graphics library, developers can directly access the GPU of a computer or mobile device to render various visual effects with high performance. Here, by using WebGL technology, pixel computation tasks are migrated to a GPU that can compute in parallel for processing. The generation efficiency and the generation speed of the final color noise vortex image are greatly improved, and particularly for complex image processing tasks, the rendering time of image generation can be remarkably reduced. And based on a Web graphic library, the method can run on various platforms supporting the WebGL by adopting the WebGL technology, so that the image generation is more convenient.
