Fig. 1 is a flowchart of a first embodiment of an image generation method provided in this disclosure, where the image generation method provided in this embodiment may be executed by an image generation apparatus, the image generation apparatus may be implemented as software, or implemented as a combination of software and hardware, and the image generation apparatus may be integrated in some device in an image generation system, such as an image generation server or an image generation terminal device. As shown in fig. 1, the method comprises the steps of:
step S101, acquiring a first image layer image;
in one embodiment, the first image layer image may be any image.
In an embodiment, the acquiring the first layer image includes: acquiring an image to be processed; and extracting a foreground image of the image to be processed as a first image layer image.
In this embodiment, the image to be processed may be obtained by an image sensor, which refers to various devices capable of acquiring images, and typical image sensors are video cameras, and the like. In this embodiment, the image sensor may be a camera on the terminal device, such as a front-facing or rear-facing camera on a smart phone, and an image acquired by the camera may be directly displayed on a display screen of the smart phone. In this embodiment, the acquiring of the image to be processed may be acquiring a current video frame of a video acquired by a current terminal device, and since the video is composed of a plurality of video frames, the processing of the image in this embodiment may be processing the video frame of the video.
In this embodiment, the image to be processed may be any image obtained from a local or network. In this embodiment, the extracting a foreground image of the image to be processed as the first layer image includes: acquiring an extraction template image of a foreground image; and superposing the template image and the image to be processed to obtain the foreground image. In this embodiment, an extraction template image of a foreground image is obtained, the template image includes a region having the same shape as the foreground image to be extracted, and the foreground image is extracted through the region having the same shape. The overlapping the template image and the image to be processed to obtain the foreground image comprises: and superposing the template image and the image to be processed in a transparency manner to obtain the foreground image. In this embodiment, the template image comprises two regions, a first region having a transparency of 0, i.e. being completely opaque, and a second region having a transparency of 1, i.e. being completely transparent. In this embodiment, the transparency of the image in the RGB color space is used to calculate the foreground image, and the image to be processed is set as G1The template image is G2Where transparency is expressed using alpha, the foreground image G can be calculated by the following formula3Comprises the following steps:
G3＝G1.alpha*G2.alpha
therefore, the required foreground image can be extracted through the transparent area of the template image.
Optionally, a specific embodiment of the template image is an image with the same size as the to-be-processed image, and a region with the same shape as the foreground image is located in the template image at a position corresponding to the foreground image of the to-be-processed image. As shown in fig. 2, 201 is an image to be processed, where 203 is a foreground image of the image to be processed 201, 204 is a background image of the image to be processed 201, and 202 is a template image for extracting the foreground image 203, where the template image includes a transparent area 205 and an opaque area, where the transparent area is the same as the shape and size of the foreground image 203, and the opaque area is a background 206, and the template image 202 is superimposed on the image to be processed 201, and since 206 is opaque and 205 is transparent, the foreground image 203 can be extracted from the image to be processed 201, and an image 207 is obtained.
It can be understood that the shape of the transparent region of the template image can be set arbitrarily, and can be set to any required shape to extract different foreground images, which is not described herein again.
Step S102: acquiring a second image layer image;
in one embodiment, the second image-layer image may be any image.
In an embodiment, the manner of acquiring the image of the second layer may be the same as the manner of acquiring the image of the first layer.
In an embodiment, the acquiring the second image-layer image includes: moving the first layer image to obtain a moving image of the first layer; calculating a superposition image of the first layer image and the moving image of the first layer according to a first logic calculation rule; and taking the superposed image as a second image layer image. In this embodiment, the image of the first image is moved, and then, a new image is generated as the second image layer image by superimposing the image of the first image with the original image. As shown in fig. 3, a specific manner of obtaining the second layer image in this embodiment is that 305 in the image 301 is extracted to obtain a foreground image, the foreground image 305 is moved to the left to obtain an image 302 and a moved foreground image 306, the images 305 and 306 are overlapped, and a second layer image 307 in the image 304 is obtained according to the following calculation logic:
G4＝！(G5and G6)and G5
wherein G is4For the final second image layer image 307, G5Is a foreground image 305, G6The shifted foreground image 306 is thus computed according to the logic described above, resulting in image 307.
It is understood that the above logic calculation rule is only an example, and the logic calculation rule in the present disclosure may be any rule, and any calculation rule may be designed as needed to obtain a desired result of the superimposed image, which is not described herein again.
Step S103: calculating a first image area after the first image layer image and the second image layer image are superposed;
in this embodiment, the calculating the first image area after the first layer image and the second layer image are superimposed includes: and calculating a first image area after the first image layer image and the second image layer image are overlapped according to a second logic calculation rule. Fig. 3 shows an example of a first image area after the first layer image and the second layer image are superimposed by calculating a second logical calculation rule, such as the image 308 shown in fig. 3, and a superimposed image of the first layer image and the second layer image, i.e. the first image area 309, is obtained by the following logical calculation rule:
G7＝G4or G5
wherein G is7Is a superimposed image. Through the above logic calculation, the second layer image 307 and the first layer image 305 are superimposed to generate a first image area 309, in which an effect that the image 307 is in the background and the image 305 is in the foreground is presented.
In one embodiment, a UV map for the first image region used for rendering may be generated.
It is understood that the above logic calculation rule is only an example, and the logic calculation rule in the present disclosure may be any rule, and any calculation rule may be designed as needed to obtain a desired result of the superimposed image, which is not described herein again.
Step S104: and rendering to generate a first image according to the first image area.
In one embodiment, the rendering the first image according to the first image area includes: and rendering to generate a first image according to the front-back relation of the first image layer image and the second image layer image in the first image area. In this embodiment, a first layer image is rendered in a first layer in the display area, and a second layer image is rendered in a second layer in the display area, and since the overlapping portion of the image of the first layer and the image of the second layer is already distinguished by logic calculation in step S102 and step S103, the rendering can be completed by one-time rendering. Specifically, a UV map of the superimposed image may be generated in the result in step S103, in which the first image is generated by rendering the color of the first image into the display area through the UV map.
In an embodiment, in the step S103, the moving the first layer image to obtain a moving image of the first layer includes: and moving the first layer image for multiple times to obtain a plurality of moving images of the first layer. In a specific example of this embodiment, the first layer image is moved by the same distance in four directions, i.e., up, down, left, and right.
In step S103, the calculating a superimposed image of the first layer image and the moving image of the first layer according to the first logic calculation rule includes: and calculating the superposed images of the first layer images and the moving images of the plurality of first layers according to a first logic calculation rule. As described in step S103, when there are a plurality of moving images of the first layer as a result of one-time superimposition, the superimposition result is repeatedly calculated, and according to the example in step S103, a superimposed image as shown in 401 in fig. 4, that is, an image in which the second layer is not wanted in this embodiment, is obtained after the first-layer image is moved in four directions, i.e., the up, down, left, and right directions and superimposed with the first-layer image according to the first logical calculation rule. Then, in step S104, the first layer image and the second layer image obtained in this embodiment may be superimposed according to a second logic rule to generate a first image area, as shown in 402 in fig. 4. Through the specific example in the embodiment, different superimposed image effects can be generated by setting a moving rule and a logic calculation rule, for example, in the specific example of the embodiment, an effect of a flower is realized, petals are located at the bottom of a flower layer of a flower center, a certain layering effect is achieved, and the effect of the flower can be generated through one-time image rendering without repeatedly rendering for 5 times.
