Data processing method based on data compression

The invention relates to the field of data processing, in particular to a data processing method based on data compression, and the method comprises the following steps: analyzing original data, and recognizing the structure, mode and redundancy of the original data; selecting a lossless or lossy compression algorithm according to a pre-analysis result, and configuring related parameters to optimize a compression effect; carrying out necessary conversion on the data, including image partitioning, audio sampling rate adjustment and possible pre-filtering, so as to adapt to the requirements of a compression algorithm; encoding the data, and reducing the encoding length by using Huffman encoding in lossless compression; the lossy compression reduces the precision of the data through quantization; packaging the coded data, adding necessary header information to ensure that the data can be correctly recovered during decompression, and storing the data in a file or a transmission medium; and after decompression, po
