LOSSLESS COMPRESSION ALGORITHM AND APPARATUS BASED ON EMBEDDED SYSTEM PICTURE, AND COMPUTER DEVICE AND STORAGE MEDIUM

WIPO Patent Application WO/2023/231265

A1

Provided in the present application are a lossless compression algorithm and apparatus based on an embedded system picture, and a computer device and a storage medium. The algorithm comprises: determining the least frequent data in source data or data in non-source data, and marking the data as node data; compiling statistics on a data length of compressible data in the source data and marking a position, so as to obtain statistical data; if the node data appears in the source data, inserting a specific character after the node data, and if the node data is the data in the non-source data, not performing any processing so as to obtain node identification data; and compressing the statistical data, and then embedding the compressed statistical data together with the node identification data into the source data, so as to obtain compressed storage data. In the present invention, clustering processing is performed on data of pictures, and the same adjacent data appearing repeatedly is replaced with data in a set format, such that the size of the data is greatly compressed; and no external storage is required for a miniature embedded system, which saves on costs and also reduces the size of a device.
