Problems solved by technology

[0004] Common texture compression algorithms include DXT (DirectX Texture, DirectX Texture Compression), ETC (Ericsson Texture Compression, Ericsson Texture Compression), etc. The above texture compression algorithms are all lossy texture compression algorithms, and the texture maps decompressed and rendered by the peer end are all Compared with the original texture map, it will bring different degrees of image quality degradation

Abstract

The invention relates to an image processing method and device, electronic equipment and a storage medium, and belongs to the technical field of computers. The method comprises the following steps: partitioning an original image to obtain a plurality of image blocks; determining a plurality of target image blocks containing foreground pixels in the plurality of image blocks; and rearranging the plurality of target image blocks to obtain a compressed image, and generating index information used for indicating the position mapping relationship of the target image blocks in the original image and the compressed image. According to the invention, the memory occupation can be greatly saved on the premise of ensuring that the image quality before and after compression is lossless.

Description

technical field [0001] The present disclosure relates to the technical field of computers, and in particular to an image processing method, device, electronic equipment and storage medium. Background technique [0002] With the development of computer image rendering technology, texture (UV) mapping is a commonly used rendering technology in a wide range of application scenarios such as video game rendering, video special effect rendering, and movie special effect rendering. For example, user selfie video The magic expressions, special effect pendants, etc. added in , can all be realized by using texture mapping technology. [0003] Although the GPU (Graphics Processing Unit, image processor) can directly read some uncompressed texture maps, if the uncompressed texture maps are directly loaded on the mobile device, it will cause high memory consumption and large transmission bandwidth. As a result, a series of performance problems such as device overheating and application ...
