US Patent 7801354 Image processing system

An image processing system includes a learning device generating, in advance, a recognizer for recognizing a recognition target; and a recognition device recognizing, using the recognizer, whether a recognition image includes the recognition target. The learning device includes model feature point generator for generating model feature points, model feature quantity generator for generating model-feature quantities, learning feature point generator for generating learning feature points, learning feature quantity generator for generating learning feature quantities, learning correlation feature quantity generator for generating a learning correlation feature quantity, and recognizer generator for generating the recognizer. The recognition device includes recognition feature point generator for generating recognition feature points, recognition feature quantity generator for generating recognition feature quantities, recognition correlation feature quantity generator for generating a recognition correlation feature quantity, and recognition processor for determining whether the recognition image includes the recognition target.
