EigenHistograms: Using Low Dimensional Models of Color Distribution for Real Time Object Recognition
14 years 1 months ago
Abstract. Distribution of object colors has been used in computer vision for recognition and indexing. Most of the recent approaches to this problem have been focused on de ning op...
