ABSTRACT:
In an apparatus for analyzing local features of a character or any other figures, an extraction of the local features is performed by correlation calculations using a plurality of first reference masks, an analysis associated with combinations of the extracted local feature is performed by pattern matchings using a plurality of second reference masks, and the extraction and the analysis are performed optically and simultaneously with respect to the plurality of reference masks, respectively. Therefore, the local features analysis can be performed at high speed and accurately.
