Similarity calculation device for calculating a correlation-based similarity of image recognition apparatus, a similarity calculation method, the recognition method, the verification program and a recording medium recording it
PROBLEM TO BE SOLVED: To provide an image similarity computation device and an image similarity computation method which can precisely compute the similarity of a pair of images, and also provide an image recognition device and an image recognition method which use the computation device and the computation method.;SOLUTION: A characteristic area setting part 45 sets T pieces of characteristic area Aj (1≤j≤T) in common in a first image I1 and a second image I2. For each of T pieces of the characteristic area Aj, a first and second characteristic quantity computation parts 46 and 47 compute an area value x1k, and x2k of pj pieces of partial area ak (1≤k≤pj) in the characteristic area Aj of the first and second images I1 and I2. Based on the area values, a correlation value computation part 48 computes a correlation value (1) in the characteristic area Aj of the first and second images I1 and I2. The correlation value Cj is compared with a threshold value θj in a comparison part 49. The result of the comparison is added by multiplying a weighting coefficient wj by means of a weighting addition part 50 to find the similarity.;COPYRIGHT: (C)2006,JPO&NCIPI
