Image Similarity Measures for Video Processing
Longin Jan Latecki · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2003
It is obvious that image histograms are of very limit use in video analysis. For example, two images containing the same objects at different positions are mapped to the same histograms. We show that a simple extension of image histograms to include the position information of the centroids of histograms bins leads to a useful representation for video analysis. This extension must be done carefully in order to obtain a representation that is stable with respect to noise. Moreover, the carefully extended histograms also add stability and reliability to the retrieval of still images.
