Abstract: According to the data processing method and system, coding spectrum adjustment can be performed on initial data, so that the amplitude of a selected area in an initial frame is smoothly reduced, the amount of data information is decreased, and the compression efficiency of data is improved. When decompressing compressed data, decoding spectrum adjustment is performed on the compressed data by using parameters corresponding to the coding spectrum adjustment, the compressed data is subtracted from the data subjected to the decoding spectrum adjustment to obtain boundary information, and the boundary information and the compressed data are superimposed to restore or enhance the amplitude of the decompressed data in the selected area. The decoding spectrum adjustment can effectively avoid the ringing effect, so that the decompressed data is clearer. The method and system can improve the compression efficiency of data, improve the transmission efficiency, and can also improve the clarity of the decompressed data.
