Fast motion estimation based on coding bits and EPZS

H.264视频编码采用快速帧间模式判决和运动估计算法,显著提高了编码效率,利用多分辨率运动估计方法和率失真模型结合编码比特数来加快搜索过程,可以减少编码时间和计算量。实验表明,在视频质量不下降的同时,在EPZS算法基础上显示了更好的性能。

Fast inter-frame mode decision and motion estimation algorithm was applied for H. 264 video coding to obviously improve the coding efficiency. We combined the multi-resolution motion estimation with rate-distortion model to code the number of bits, for obtaining the fast searching process to reduce both the time and the amount of computation. Experiments showed that the property of the method was better than the EPZS algorithm with the satisfied video quality.
