JPEG, the younger brother to contact about the algorithm, the algorithm will put the figure into n 8 by 8 block, and then has a regulation frame head, excuse me, is the last block independent set of frames, a picture contains n independent block frame? Or say a picture frame 1, just block compression information will have the index to instructions? Thank you very much!

JPEG image compression process:
The whole image can be divided into several, 8 * 8 matrix
For each of the 8 * 8 matrix DCT transform
After the DCT quantization matrix of
To ZIGZAG order
The DC component and AC components separately DPCM and RLE coding
The whole information of Huffman coding
