| Abstract: | According to the bidirectional forecast motion compensation as well as the dynamic auto-adapted adjustment characteristic of lifting wavelet transformation,the neighboring picture quality fierce fluctuation flaw produced by the MPEG-4 standard coding is adjusted,carriing on the compression of the image which was adjusted using the algorithm that obtained by transect approaches using three spline functions.Through the image analysis and simulation,this method improves the picture quality and the compression ratio,at the same time optimizes the edge effect. |
