Abstract:
Using the integer Discrete Cosine Transform(DCT),H.264 avoids the mismatch problem,and increases the computation speed and make hardware implementation easy.This paper analysed the principle of the H.264 integer DCT and fast papilionaceous algorithm,and changed its transform core,simulated the new core using MATLAB.The results show that integer DCT with new transform core is closer than DCT,and enhances the subjective quality of reconstruction image.
