1.首先通过DCT变换去除数据冗余;
2.使用量化表对DCT系数进行量化;
3.对量化后的系数进行Huffman编码。
具体源程序由主程序及两个子程序(DCT量化、Huffman编码)组成:
,1. First of all, through the DCT transform to remove data redundancy 2. The use of quantization table of quantization DCT coefficients 3. Of quantization of the coefficients after Huffman coding. Specific source from the main program and two subroutines (DCT quantization, Huffman encoding) consists of:
