摘要

讨论了几种块匹配运动估计算法，以确定在极低比特率视频编码(使用H.263 CODEC)中使用的最佳技术。研究了预测误差函数、搜索方法和简化技术，以确定低运动序列(头肩序列)和高运动序列编码过程中使用的整体块匹配策略。

On the performance of block matching techniques for very low bit rate video coding

Several block matching motion estimation algorithms are discussed in order to determine the best techniques to use in very low bit-rate video coding (H.263 CODEC is used). Prediction error functions, search methods and simplified techniques are studied to determine the overall block matching strategy to use in the coding process of low movement sequences (head and shoulder sequences) and high movement sequences.
