Abstract

The most computationally expensive operation in entire video compression process is Motion Estimation. The challenge is to reduce the computational complexity and time of Exhaustive Search Algorithm without losing too much quality at the output. The proposed work is to implement a novel block matching algorithm for Motion Vector Estimation which performs better than other conventional Block Matching Algorithms such as Three Step Search (TSS), New Three Step Search (NTSS), and Four Step Search (FSS) etc.

一种新的小块匹配算法用于视频压缩中的运动矢量估计
在整个视频压缩过程中,计算开销最大的操作是运动估计。如何降低穷举搜索算法的计算复杂度和时间,同时又不影响输出的质量,是当前搜索算法面临的挑战。提出了一种新的运动矢量估计块匹配算法,其性能优于传统的块匹配算法,如三步搜索(TSS)、新三步搜索(NTSS)和四步搜索(FSS)等。
