DCT
读入一幅256*256图像,将它分成8*8pixel的若干块,对每块做DCT变换,保留Z型顺序的若干变换系数,进行IDCT重构图像,计算重构图像的信噪比(Reading a 256* 256 image, it will be divided into several blocks of 8*8 pixel, keep each optimal Z transformation of sequence number, IDCT transform coefficient calculation reconstruction image reconstruction images,and the signal-to-noise ratio)
