Google Tech TalksFebruary 2, 2007ABSTRACTWe present a new approach for semantic image analysis that combines knowledge of human perception with an understanding of signal characteristics to segment natural scenes into perceptually uniform regions, and then uses the region statistics to extract semantic information that can be used for intelligent and efficient image organization and retrieval.
