| Abstract: | In order to solve the block effect problem when the video is coded or decoded, the picture smooth block algorithm suitable for the H. 264 standard is proposed by through researching and comparing various smooth block algorithms. The improved algorithm and its implementation process are discussed in detail. The new processing sequence is given and the boundary smooth block strength calculation formula is derived. The test results indicate that the proposed algorithm＇ s running time becomes shorter, storage space less, and performance is raised. |
