Analysis of H.264 Motion Estimation Algorithm
Huang Shi-tan · Computer Technology and Development · 2009
As a new video compression coding standard,H.264 has low bit rate,high quality and high compression ratio characteristics,but it costs highly computational complexity and memory spending,especially in motion estimation part.Therefore,according to the characteristics of H.264,it is a hot issue to find out a fast motion estimation algorithms in recent researching.Describes the basic principle and the esse ntial technologies of the H.264 video coding standard.Introduces several popularly fast block matching motion estimation algorithms,including full-search algorithms and fast-search algorithms,and analyzes their advantages and disadvantages.The hexagon algorithm is used universally,so introduces a simplification algorithm and analyses the hexagon search.
