Triangular segmentation criterion for DT mesh based video coding

Based on the analysis of the deficiency of two previous Delaunay triangular mesh segmentation criterions—minimize difference of gray and minimize variance of gray, a new triangular mesh criterion, minimize sum of squared difference of gray, was proposed. The new segmentation was more rational and ef...
