PROBLEM TO BE SOLVED: To provide a method of detecting recessed points on the outline of a region contained in a binary image, in order to segment the region into a plurality of partial regions. SOLUTION: A projecting region is defined on condition that pixels outside of the region do not exist inside a projecting envelope created out of regions. Underneath it is the outline of the region that divides the region into a plurality of sections where the region becomes projecting regions locally, and connections between the sections are recessed points. In this way, it is possible to detect the recessed points without having to determine parameters empirically. COPYRIGHT: (C)2010,JPO&INPIT
