Problems solved by technology

[0004] However, the first method is image lossy coding, and the calculation process is relatively complicated, which will affect the image compression efficiency; for the single image compression based on redundant information in the second method, the compression rate is limited. If there are a large number of pictures in the same web page, the loading speed of the web page will also be slowed down accordingly, that is, the loading speed of the web page is still largely affected by the number of pictures

Abstract

The present invention provides an image compression method, an image compression device, an electronic device and a storage medium, and relates to the field of data processing technology. The method comprises: acquiring matrices corresponding to a plurality of channels of an image, and performing bitwise layering on each of the matrices; performing correlation calculation on matrices correspondingto each layer of each channels after bit layering, and obtaining a difference matrix corresponding to the correlation; performing stroke length coding compression to the difference matrix, and generating and storing a plurality of data tables corresponding to the channels of the image. The method can improve image compression rate and image transmission efficiency.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular, to a picture compression method, a picture compression device, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the rapid development of e-commerce, for major website platforms, their internal systems will store a large number of pictures, for example, there will be a large number of product pictures and product detail pictures in e-commerce websites. Since the processing of massive pictures and data consumes a large amount of storage media and transmission bandwidth, it is necessary to compress massive pictures to improve storage and transmission speed. [0003] In the related art, there are two methods for compressing massive pictures: the first method considers the visual characteristics of the human eye, such as chroma sampling and change coding methods; the second method is based on the Joint Photographic Exp...
