Jikun Guo · Communications technology · 2009
This paper first discusses the deformable block model based on the displacement nodes,and analyzes the search process and flow of NS-DBMA algorithm,then proposes the motion estimation algorithm by node search based on deformable block matching with threshold.Four-node model as an example,the paper further studies the technical flow of the algorithm,and the test by two sequences is done,the test results show that forecast images effect of TNS-DBMA algorithm is close to NS-DBMA algorithm,and however,the TNS-DBMA algorithm greatly reduces the computational complexity,at least to half as much as that the NS-DBMA algorithm does.
