Abstract

The invention discloses an image compression method and device. The method comprises the steps: carrying out the dividing of an image, and obtaining a plurality of image blocks; carrying out the compression of each of the image blocks, and obtaining preferable compression data; carrying out the combination of the preferable compression data obtained through the compression of each image block, obtaining a compression result of the image, obtaining the preferable compression data through the compression of the image blocks, and obtaining the compression result according to the preferable compression data, thereby achieving the technical effect of achieving high-efficiency and accurate compression through employing a direct compression method, and solving technical problems that the image features are complex for recognition in related technologies, and the image compression quality is not high.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image compression method and device. Background technique [0002] In the related art, when compressing images, different compression ratios and image restoration qualities will be obtained due to the compression and encoding of different types of images with different compression algorithms. Therefore, in order to achieve better compression quality, in the related art , generally by using a variety of methods to analyze the image characteristics, select the compression algorithm with the best image compression quality, and compress the image according to the selected compression algorithm. However, when analyzing image features, the algorithm for identifying image features is relatively complex and the accuracy is not high, which leads to inaccurate selection of image compression algorithms, and finally the quality of image compression is not high. [0003] Therefore,...
