| Abstract: | In this paper, the prevailing image compression criteria are introduced. Through analyzing the H.263 algorithm, the three improvements are presented. And the DCT/IDCT fast algorithm is discussed and by adopting the MMX technology, the modules about these are designed. In the end, the whole of software video surveillance system is well implemented and proved to be excellent though actual utilization. |
