Abstract
The object of the present invention is to enable high-speed and high-precision pattern retrieval. Therefore, a retrieval dictionary generation unit classifies learned patterns into plural clusters, and generates a retrieval dictionary using the clusters. A nearest cluster detector detects the nearest cluster to an input retrieval pattern among clusters stored in the retrieval dictionary. A learned pattern detector compares each learned pattern which belongs to the nearest cluster with the retrieval pattern and detects a learned pattern at predetermined distance from the retrieval pattern. A retrieval range decision unit decides a retrieval range using the learned pattern detected by the learned pattern detector and retrieval information. A retrieval unit executes the retrieval of the retrieval pattern from among all the learned patterns in the retrieval range.
