Abstract:
A recognition apparatus for recognizing a given subject from different types of input data, comprising:a first classification data construction unit for constructing a first set of classification data from the different types of input data; a first classification unit for classifying the different types of input data into a first class based on the first set of classification data from the first classification data construction unit; preprocessing means for extracting a plurality of characteristic parameters from the different types of input data on the basis of said first class from said first classification unit; a second classification data construction unit for constructing a second set of classification data based on the plurality of characteristic parameters from the preprocessing means; a second classification unit for classifying the different types of input data into a second class based on the second set of classification data from the second classification data construction unit; an integrated parameter construction unit for constructing an integrated parameter by integrating the plurality of characteristic parameters from the preprocessing means; a plurality of standard parameter memories for storing a plurality of tables; each standard parameter memory corresponding to a predetermined first class; each table containing standard parameters corresponding to a predetermined second class; and a matching unit for recognizing the given subject by matching the integrated parameter with the standard parameters from the table corresponding to the second class and located in the standard parameter memory corresponding to the first class.
