Recently proposed colour methods for optical flow recovery axe compared with traditional, gray-scale methods. New methods are presented which extend gray-scale methods into colour. Colour methods are shown to perform acceptably when compared to their gray-scale counterparts.
During this research an extensible application was created to enable efficient comparison of various optical flow techniques by researchers and students. It features custom image sequences, synthetic ground-truth creation, custom pre-filtering, differentiation, optical flow methods (both gray-scale and colour) and flow analysis through image reconstruction, density/sparsity analysis, ground-truth analysis and flow visualisation.
