| 摘 要： | 视频信息具有一系列的优点,但是原始视频信息包含的数据量非常庞大,视频压缩编码使得视频应用得到了推广。然而在视频编码器中,运动估计/补偿模块消耗了大量的编码时间及系统资源。对其中的1/2像素精度运动估计进行了算法优化,提出了新型的插值构架,以较低的复杂度完成了较好的硬件加速功能。

| Abstract: | Video information has a number of advantages,but the original video information contains a very large amount of data,video compression makes it easier to come to applications.However,the motion estimation / compensation is the most time-consuming part in a video encoder,and takes up a lot of system resources.In this paper,an optimized algorithm and the corresponding architecture are proposed,accelerating the function with a lower complexity. |
