Description: image compression defined pixel sequence (p1, p2, ..., pn) sub-optimal, sub accordingly makes the storage space required at least. The length of each section is not more than 256. The digital image is m m pixel arrays. Assume that each pixel is a 0-2 5 5 of the gray values. Therefore storage of up to a pixel 8. If each pixel with the largest storage capacity of 8-bit, the total storage space for 8m ^ 2. In order to reduce storage space, and we will use variable-length model (variable bit scheme), that is different with different pixel median storage. Pixel values of 0 and 1 and only a storage space; The value of 2,3 required two; Value 4,5,6 and 7 of the required three; Analogy.
