Abstract

The invention discloses a picture processing method, an intelligent terminal and a storage medium, and the method comprises the steps: carrying out the lossy coding processing of an input picture, extracting the features of the picture, and carrying out the quantification processing of the features into a feature graph; performing lossless coding processing on the feature map to obtain a feature value and a probability value of the feature map, merging the feature value and the probability value, and performing arithmetic coding to form a binary file; performing lossless decoding processing on the binary file to obtain the feature map; and carrying out lossy decoding processing on the feature map to restore the picture. According to the invention, intermediate files generated by image compression are reduced, the compression ratio is improved, and the image can be compressed to be smaller.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, an intelligent terminal and a storage medium. Background technique [0002] Videos and pictures are common information carriers in daily life. However, lossless pictures occupy a lot of physical storage space and are not conducive to transmission. A key technology for picture compression is entropy coding (entropy coding is based on the probability that characters are estimated For encoding, the more accurate the estimated probability, the higher the file compression ratio. For example, the original file size is 50M, and after compression it is 25M, and the compression ratio is 2. The higher the number, the smaller the file can be compressed; the encoding process Entropy coding can losslessly compress the intermediate files generated by image compression. [0003] Entropy coding can be divided into two parts: the probability estimatio...
