Xinbo Gao · Computer Technology and Development · 2008
Improvement to the search window of MVFAST algorithm is proposed,on the basis of analyzing MVFAST algorithm.By its improvement,and in the guarantee of image quality,the search speed of algorithm is improved.Designs the architecture and processing element.At the same time,the architecture for flexible data flow and search strategy is proposed.Tests different video sequences,video sequences on different resolution and video sequences on different motion degree,experiment results verify that the processing speed of the architecture is improved obviously,the memory accessing bandwidth is reduced dramatically,and its image quality is similar to the full search algorithm.
