VIDEO PROCESSING METHOD AND APPARATUS, DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/029892
Kind Code:
A1
Abstract:
The embodiments of the present disclosure relate to a video processing method and apparatus, a device, and a storage medium. The method comprises: acquiring three-dimensional reconstruction data of a video image and a first texture image corresponding to a current moment; according to a pre-obtained mapping relationship between pixel positions and initial brightness and brightness change rates, determining that a target pixel position on the first texture image corresponds to target brightness at the current moment; adjusting the brightness of the target pixel position on the first texture image to be the target brightness so as to obtain a second texture image; and on the basis of the three-dimensional reconstruction data, mapping the second texture image onto the video image so as to obtain a target video image. Thus, the same pixel position on a video image may show different textures and brightnesses at different moments, and different pixel positions on the video image may show different textures and brightnesses at the same moment, thereby implementing a flowing and flickering texture effect on the video image, which makes the video more interesting.
