Deformation and Viewpoint Invariant Color Histograms
Justin Domke, Yiannis Aloimonos · 2006
We develop a theoretical basis for creating color histograms that are in-variant under deformation or changes in viewpoint. The gradients in differ-ent color channels weight the influence of a pixel on the histogram so as to cancel out the changes induced by deformations. Experiments show these histograms to be invariant under a variety of distortions and changes in view-point. 1
