PATTERN IDENTIFYING SYSTEM, PATTERN IDENTIFYING METHOD, AND RECORDING MEDIUM FOR RECORDING A PATTERN IDENTIFYING PROGRAM

摘要

As to the present invention provide a pattern identification system, a pattern identification method, a pattern identification program that can guarantee the precision of calculation can be improved, and also, secure a stable strength of the mobility, ohsuri probability, ; Pattern identification system (10, 10a) is, the first probability and the calculating part 32, the first having a second probability calculation unit 33 connected to a probability calculation section (32). A first plurality of corresponding feature points representing a plurality of points corresponding to the probability calculation section 32, a first plurality of characteristic points (s1 to sn _s) and the second plurality of characteristic points (f1 to fn _f) of the pattern of the pattern ( on the basis of the cs1 to csn, number (n) of cf1 to cfn), calculates a first probability (P _FCR). A first probability (P _FCR), the number of corresponding feature points (n) than the probability that there is a third pattern having a larger number of corresponding characteristic points to the first pattern. 2 calculates the probability calculation section 33, a first probability (P _FCR) ohsuri probability (P _FAR) illustrating a probability that the first pattern and the second pattern to be invalid by referring to the correspondence.
