Document Type and Number:

WIPO Patent Application WO/2008/044380

Kind Code:

A1

Abstract:

Provided is a pattern recognizing device (1) comprising a collation vector extracting unit (823) for generating an input collation vector composed of a predetermined number of components exhibiting the features of an input pattern and each indicating 1 or 0, and a collation vector coincidence deciding unit (824) for calculating a coincidence based on the inner product between each of the dictionary collation vectors read from a dictionary collation vector storing buffer (813) and the input collation vector. A collation is made between a dictionary featuring vector, for which a coincidence larger than a predetermined threshold value is calculated, and the input collation vector. A dictionary pattern corresponding to the dictionary collation vector, which is so decided on the basis of the collation result as to coincide with the input collation vector, is read from a dictionary data (811) and is outputted.
