Abstract
PURPOSE: To extend virtually the peculiar line terminal point extracted and to ignore the peculiar line on the extended line of which pattern stroke exists. Thus, the peculair line of contour pattern is extracted for the recognition object pattern. In this way, high-speed processing become posisble.
