A Delaunay Mesh-based Motion Estimation and Compensation Scheme based on Redundant Wavelet Transform[J]. Journal of Image and Graphics, 2007, 12(12): 2072. DOI: 10.11834/jig.20071207.
a new motion estimation and motion compensation scheme based on irregular mesh is proposed using a shift invariant redundant wavelet transform.Control points and PMA(potential motion areas)are identified with a simple correlated operator in the redundant wavelet subbands
while motion estimation is completed through incorporating the PMA into block matching algorithm in spatial domain.The motion compensation is realized through an affine transform mapping triangles from one frame to the other.Furthermore
we give a mask of the PMA.We compared it empirically to the two other ME/MC methods both based on regular mesh deployed in the spatial and based on irregular mesh deployed in the redundant wavelet domain.Experimental results indicate that the complexity has been reduced and the compensation effect could be improved compared to the other two ME/MC methods.
