Abstract:
1. A pattern recognition apparatus that recognizes a class of an input object pattern, the apparatus comprising: circuitry functioning as: a correlation value calculation unit configured to calculate a correlation value between a feature quantity of each local area in the input object pattern and a feature quantity of a corresponding local area in each of registered object patterns in a dictionary in which at least one object pattern has been registered for each of predetermined classes and a plurality of object patterns have been registered for at least one of the predetermined classes; a combining unit configured to combine, for each class of the predetermined classes, the correlation values calculated for respective registered object patterns which belong to that class with respect to each local area in the input object pattern; an obtaining unit configured to obtain an integrated similarity of the input object pattern for each class of the predetermined classes by integrating the combined correlation values of a plurality of local areas for that class; and an identification unit configured to identify a class of the input object pattern based on the integrated similarity for each class obtained by said obtaining unit.
