THE FAST SEARCH MOTION ESTIMATION ALGORITHMS AND THEIR ERRORS
Ján Gamec, Mária Gamcová · 2008
This paper presents the analysis of errors produced by block matching motion estimation methods with lower computational cost (fast search algorithms). We try to find an answer on the question what measure can be used to determine correctness of searched motion vectors and which motion vectors are founded as fault (corrupted by noise). We consider the vector fields obtained by using of full search algorithm (FSA) as lossless data. We take the vectors of movement obtained by using 2D logarithmic (2D log) search procedure as data corrupted by noise. The results of analysis can help optimize post processing of motion vectors in endeavoring to reduce computational cost or regularize vector fields.
