| 摘 要： | 给出了一种针对H.264解码器中运动补偿模块的有损优化算法,旨在减少H.264解码器的总运算,以更好地适应便携式设备。算法主要对运动补偿模块中的1/2像素和1/4像素插值滤波器进行了优化。由实验结果可知,该算法能够有效地降低运动补偿模块的运算量,同时不会引起明显的视频质量的降低和漂移效应。

| Abstract: | An optimized algorithm with image quality loss for motion compensation module in H.264 decoder is proposed.The purpose of the algorithm is to reduce the total computational cost of H.264 decoder to let it perform better on portable device.The algorithm is mainly optimized for the 1/2-pel and 1/4-pel interpolation filter.The experimental results show that this algorithm can reduce the computational cost of motion compensation module without causing significant distortion and drift in decoded image. |
