ABSTRACT:
In a page segmentor for dividing a page into areas each having a single feature, the division being performed as preprocessing for pattern recognition, one of the areas within the page is multiplied into multiple images, a feature of each area is extracted according to the presence or absence of each of pairs between the multiple images and a plurality of different masks, and the page is divided into areas until each area has a single feature. High-speed page segmentation can be achieved so as to obtain a desired feature.
