図形認識における領域カウンタとその応用

図形の面的処理の一方法

抄録

The author presents a region counter and its several applications in the field of pattern recognition. The outline of this paper is as follows.
(1) The region counter is an apparatus which counts the number of regions divided or occupied by a pattern. From the basic experiment of a region counter, the author has concluded that a practical counter can be constructed.
A method for the feature extraction of pattern using this region counter is presented. From a simulation of the hand written numeral reader, it is found that this method is useful to extract the topological features of a pattern.
(2) The author presents a new method to determine automatically the threshold value in reading a pattern optically. The experiments have shown the possibility of an automatic setting of the threshold value.
(3) A method to break up the pattern having some blobs such as those in a Chinese Character into blobs, and the principle to realize this method by hardware are given. It is confirmed experimentally that a useful device can be manufactured.
