METHOD AND APPARATUS FOR ENCODING AND DECODING IMAGE BASED ON CODE TABLE SELECTION ADAPTED TO RESIDUAL VALUE DISTRIBUTION

摘要

A method and apparatus are provided for encoding and decoding an image which entropy encode and decode a residual value of a current pixel in consideration of a context model determined with reference to at least one pixel value that is encoded and decoded before the current pixel and distribution of the residual values encoded and decoded according to the determined context model.
