ABSTRACT:
A pattern recognition system, pattern recognition method, and pattern recognition program capable of increasing the accuracy in computing the false acceptance probability and capable of ensuring a stable security strength are provided. Pattern recognition systems10and10acomprise a first probability computation unit32, and a second probability computation unit33coupled to the first probability computation unit32. The first probability computation unit32computes a first probability PFCRbased on the number n of corresponding characteristic points cs1to csn and cf1to cfn indicating points corresponding between characteristic points s1to snsin a first pattern and characteristic points f1to fnfin a second pattern. The first probability PFCRindicates the probability of existence of a third pattern that has a greater number of corresponding characteristic points to the first pattern than the number n of the corresponding characteristic points. The second probability computation unit33refers to the first probability PFCRto compute a false acceptance probability PFARindicating the probability of falsely determining that the first pattern and the second pattern correspond to each other.
