Research Of Inter-code In H.264

The thesis mainly discusses the inter-code technic of H.264 video compress standard , researches the alternative-algorithm to the macroblock-division mode of H.264 in detail. It uses the class-alternative algorithm to divide the macroblock instead of the algorithm of all-proved and quicks choice to macroblock divide mode , decreases the computer process. Improves the speed of fast mode decision. At the same time , in the thesis it also analyses the motion vector fast research algorithm in the test-model and presents a new motion vector fast research algorithm. It reduces the count of search by using the relativity between the macroblocks. We test it by the standard testing-sequence with the software of Matlab.The experimental results show that the combined proposed methods provide significant improvement in processing speed without noticeable coding loss.
