Abstract:
1. An image recognition method for operating on shape data expressing an original region image to obtain shape data expressing a region image in which specific small regions have been eliminated, comprising repetitive execution of a series of steps of: selectively determining respective regions of said original region image as constituting a set of small regions which are each to be subjected to a region combining operation; selecting one of said set of small regions as a next small region which is to be subjected to said region combining operation; for each of respective regions which are disposed immediately adjacent to said next small region, calculating a length of common boundary line with respect to said next small region, and determining one of said immediately adjacent regions which has a maximum value of said length of boundary line; and combining said next small region with said adjacent region having the maximum length of common boundary line.
