Abstract

The embodiment of the invention discloses an image compression method and device, electronic equipment and a storage medium. The image compression method specifically comprises the steps of acquiring an image to be compressed; determining a target coding group of the to-be-compressed image, wherein the target coding group comprises a first coding method and a second coding method, and / or a third coding method and the second coding method; performing coding compression processing on the to-be-compressed image according to the first coding method and / or the third coding method in the target coding group to obtain a coding result parameters; and according to the second coding method in the target coding group, carrying out coding compression processing on the target coding result parameter in the coding result parameters again. According to the technical scheme provided by the embodiment of the invention, lossless compression of the image can be realized, the image compression rate and the image compression ratio are improved, and the image compression effect is further improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to an image compression method, device, electronic equipment, and storage medium. Background technique [0002] The purpose of image compression is to represent the image with as few bits as possible, while maintaining the quality of the restored image as best as possible, so that it meets the requirements of the intended application. [0003] Existing image compression methods include lossless image compression methods and lossy image compression methods. However, the image compression ratio of the existing lossy image compression method is relatively high, which will cause image compression distortion and make the image compression effect poor; the image compression rate of the existing lossless image compression method is relatively slow, the image compression ratio is low, and the compression The resulting image compression effect is poor. ...
