Abstract

The embodiment of the invention provides an image processing method and device, electronic equipment and a memory medium and relates to the technical field of image processing. The method comprises the steps of dividing a gray image of an original image into a plurality of blocks; carrying out layout analysis on each block in the plurality of blocks, thereby determining a type of each block; filling in a foreground layer, a mask layer and a background layer of each block according to the type of each block; and compressing the foreground layer, the mask layer and the background layer of each block, thereby obtaining a compressed image. According to the technical scheme provided by the embodiment of the invention, image pixel values can be filled in contiguously, fidelity is realized, and an image compression ratio is further improved.

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 have higher and higher requirements for image quality, and more and more high-resolution images are produced. How to compress high-resolution images has become the focus of attention. [0003] At present, the commonly used image compression methods include JPEG (Joint Photographic Experts Group) compression method, PNG (Portable Network Graphics, portable network graphics) compression method, and so on. However, these image compression methods can only compress on the basis of the original image, and it is difficult to further increase the image compression rate while maintaining fidelity. [0004] Therefore, how to further increase the image compression rate whi...
