An Improved Block Matching Criterion
Shen Yu-li · Radio Engineering of China · 2008
Block matching algorithm is the core technology of video coding.Throu gh block matching algorithm,the residue and motion vector between the current b lock and its matching block are obtained and thus encoded,which greatly enhance s compression ratio.On the basis of the mostly used block matching criterion,a n improved one for motion estimation in vedio encoding is proposed.The mean squ are error relative to the original pixel gray-values is calculated,at the same time,a penalty term is added into this criterion.Simulation experiments show i ts effectiveness.
