摘要：
Motion estimation search occupies most time of H.264 encode, Full Integer Motion Search is adopted by motion estimation search in encode model. But the asthmatic quantity of Full Integer Motion Search is too large, and could not be applied in some real time system. Fast Integer Motion Search suitable for H.264 is realized in this paper. This algorithm utilizes different motion characteristics of different images, adopts different search algorithms according as images with different motion characteristic separately. The test results show that this algorithm reduces 84.92% of motion estimation time when the Signal-to-Noise decrease less than 0.1%.
