用matlab实现zigzag扫描程序。-using Matlab achieve Zigzag scanning procedures.

This a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN -

Inverse zig zag scan used after zigzag scan to arrange the data back to 2d matrix or image
