Variable length coding method and variable length decoding method

摘要

5 A method for decoding a coded block image, the method comprising performing variable-length decoding on coded transform coefficients from a high frequency component toward a low frequency component to obtain decoded transform coefficients, inverse scanning the decoded 10 transform coefficients to obtain inverse-scanned transform coefficients and inverse frequency transforming the inverse-scanned transform coefficients to obtain a block image. 2216832 _1 (GHMattcrs) 10/03/10 .- n 0 a L ) () gH c 0cc U) CC' S- 0 'D* CL Cl)
