Description: 在视频处理中经常要用到Zigzag序号及其逆序号，本文提供了一个新的类CZigzag，可以求任意m×n块的Zigzag序号及其逆序号。 由于所求的Zigzag序号及其逆序号为一次性遍历生成，其时间复杂度仅为O（m×n）。-In video often use to deal with the serial number and its reverse No. Zigzag, the paper provides a new category CZigzag, can seek arbitrary m × n block Zigzag its serial number and its reverse. Zigzag As the demand for its serial number and its reverse traversal generates one-time, its time complexity is only O (m × n).

Description: blkproc.m,DCHuffmanEncoding.m,ACHuffmanEncoding.m,zigzag.m,PSNR.m,
对灰度图像进行DCT变换,量化,ZigZag扫描,Huffman编解码,反量化,反DCT变换而重建图像。
其中，blkproc.m为分块DCT变换函数；
DCHuffmanEncoding.m，ACHuffmanEncoding.m分别为DC和AC变换系数的Huffman码表函数；
zigzag.m为ZigZag扫描函数；PSNR.m为求图像峰值信噪比函数。
