Abstract

Embodiments of the present invention provide an image processing method, device, electronic equipment, and storage medium, and relate to the technical field of image processing. The method includes: dividing the grayscale image of the original image into a plurality of blocks; performing layout analysis on each block in the plurality of blocks to determine the type of each block; filling the space of each block based on the type of each block A foreground layer, a mask layer, and a background layer; compressing the foreground layer, the mask layer, and the background layer of each block to obtain a compressed image. The technical solution of the embodiment of the present invention can realize continuous filling of image pixel values, and further improve image compression rate while maintaining fidelity.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular, to an image processing method, an image processing device, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the development of image processing technology, people's requirements for image quality are getting higher and higher, and more and more high-resolution images are generated. How to compress high-resolution images has become the focus of attention. [0003] Currently, commonly used image compression methods include JPEG (Joint Photographic Experts Group, Joint Photographic Experts Group) compression method, PNG (Portable Network Graphics, portable network graphics) compression method, and the like. However, these image compression methods can only compress the original image, and it is difficult to further improve the image compression rate while maintaining fidelity. [0004] Therefore, how to further impr...
