Comparative Research on Several Classical Rapid Algorithms of Block-matching Motion Estimation
Minlian Xiao · Computer Knowledge and Technology · 2010
Block-matching motion estimation was adopted by many video standards to eliminate the temporal redundancy information be-tween successive frames,and usually the motion estimation is the most time consuming part of the whole encoding process.Many rapid motion estimation algorithms are developed in the past twenty years successively.This paper firstly analyzed the three classical rapid block-matching motion estimation algorithms.Then these algorithms were inserted into the H.264/AVC reference software.The three classic rapid block-matching motion estimation algorithms'performances were tested under the same condition.Finally,the characteristics of the three classical rapid algorithms were summarized according to the experimental results.
