针对运动估计非常耗时这一特点,本文从算法和代码两个方面对运动估计进行优化。实验证明改进后的算法明显减少了编码时间,而图像质量只有少量变化。
Aiming at the characteristic of time-consuming motion estimation, this paper optimizes motion estimation from two aspects of algorithm and code. Experiments show that the improved algorithm significantly reduces the encoding time, while the image quality changes only slightly.
