摘要

本工作提出了在不损失图像质量和压缩比的情况下优化基线H.264编码器的算法。提出一种自适应模式决策算法，利用速率失真优化(RDO)加速复杂模式决策。我们还使用单指令多数据(SIMD)指令优化计算密集型模块。因此，所提出的编码器比JM72参考编码器快十倍。

Optimization of H.264 encoder using adaptive mode decision and SIMD instructions

This work presents algorithms that optimize the baseline H.264 encoder without loss of image quality and compression ratio. We propose an adaptive mode decision algorithm to speedup complex mode decision with rate distortion optimization (RDO). Also we optimize computation-intensive modules using single instruction multiple data (SIMD) instructions. As a result, the proposed encoder is ten times faster than the JM72 reference encoder.
