Problems solved by technology
[0002] In related technologies, the pose of the object in the image is usually changed by optical flow and other methods to generate an image of the object after the pose change. However, in the generated image, only the position of each pixel is changed, and it is difficult to reflect the pose of the object. Change
Moreover, after changing the posture, the parts of the object that can appear in the image are different. For example, if the side image of the object is generated according to the front image of the object, then in the generated image, some parts of the object cannot appear in the image. In the generated image, some parts of the object that are not presented in the frontal image should be presented in the side image, and the visibility of parts of the object cannot be changed by methods such as optical flow, resulting in distortion and artifacts in the generated image and so on

The present disclosure relates to an image generation method and device, an electronic device, and a storage medium. The method includes: according to the first pose information corresponding to the initial pose of the first object in the image to be processed and the second pose information corresponding to the target pose Pose information, obtaining an optical flow graph between the initial pose and the target pose and a visibility map of the target pose; generating a first image according to the image to be processed, the optical flow map, the visibility map, and the second pose information. According to the image generation method of the embodiment of the present disclosure, the visibility map can be obtained according to the first posture information and the second posture information, the visibility of each part of the first object can be obtained, and the target posture can be displayed in the generated first image The visible portion of the first object improves image distortion and reduces artifacts.
Description
technical field [0001] The present disclosure relates to the field of computer technology, and in particular to an image generation method and device, electronic equipment and storage media. Background technique [0002] In the related art, the pose of the object in the image is usually changed by methods such as optical flow, and an image of the object after the pose change is generated. However, in the generated image, only the position of each pixel is changed, and it is difficult to reflect the pose of the object. Change. Moreover, after changing the posture, the parts of the object that can appear in the image are different. For example, if the side image of the object is generated according to the front image of the object, then in the generated image, some parts of the object cannot appear in the image. In the generated image, some parts of the object that are not presented in the frontal image should be presented in the side image, and the visibility of parts of the...
