【Graph program】 dct DL : 0: 本人根据公式用VC++做出的DCT变换源码，解说清楚。转换矩阵8*8，计算结果与MATLAB计算结果比较，两者几乎一样(相差仅 0.001)，估计是计算误差，经过我的实践证明并不影响使用。-According to the formula I use VC++ source code to the DCT transform, to clarify. Conversion matrix 8* 8, the calculation results compared with the MATLAB calculation results, the two are almost identical (a difference of only 0.001), it is estimated that the calculation error, after I prove that the practice does not affect use.
