Abstract

The invention discloses a picture-based lossless compression method, an intelligent terminal and a storage medium. The method comprises the steps: carrying out lossy coding of an input original picture, and extracting a plurality of feature maps; carrying out lossless coding on the plurality of feature maps to obtain a binary file; carrying out lossless decoding on the binary file to obtain a plurality of feature maps; and carrying out lossy decoding on the plurality of feature maps to obtain the original picture. According to the invention, the original picture is compressed into the binary file, so that the storage occupancy rate is reduced, the transmission speed of the picture can be improved, the flow is saved, and the binary file is decoded when the picture is displayed.

Description

technical field [0001] The present invention relates to the technical field of picture processing, in particular to a picture-based lossless compression method, an intelligent terminal and a storage medium. Background technique [0002] Pictures are a common information carrier 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 (coding that does not lose any information according to the principle of entropy during the coding process. ), entropy coding can losslessly compress the intermediate files generated by image compression. [0003] Entropy coding is to encode characters according to the estimated probability. There are many ways to estimate the probability. For example, three letters appear in sequence in a text: A, B, and A. The simplest way is to put the characters where A appears The number of times / total number of letters is used as the e...
