Abstract

The invention discloses an image compression method and device. The method comprises the following steps: partitioning an image to obtain a plurality of image blocks; respectively compressing each image block in the plurality of image blocks to obtain preferable compressed data; combining the optimal compression data obtained by compressing each image block to obtain a compression result of compressing the image; compressing the partitioned image blocks to obtain the preferred compressed data, and obtaining the compression result according to the preferred compressed data, so that the technical effect of realizing efficient and accurate compression by adopting a direct compression method is achieved. Therefore, the technical problems of complex image feature recognition and low image compression quality in the prior art are solved.

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,...
