Abstract:

Targeted to a series of problems, e.g., numerous data brought by the transmission of multimedia information; different requirements on picture quality from different consumers, we study the still image scalable coding, improve the base layer coding strategy and propose a classified FGS(Fine Granularity Scalable) image  coding based on the histogram scanning. This method classifies the gray levels base on the probability that the pixels appear and then code the value of the pixels with different precision based on the classes they belonged. The different requests of the consumers will be satisfied through the interactive operation.

Key words: scalable coding, fine granularity scalability coding, wavelet transform, bit-plane coding
