CHARACTERISTIC ATTRIBUTE CALCULATION DEVICE, CHARACTERISTIC AMOUNT EXTRACTION DEVICE, PATTERN MATCHING DEVICE, METHOD, AND PROGRAM |
摘要 |
An object of the present invention is to provide an apparatus that can accurately detect the correspondence relation of pattern features even when a pattern is deformed. The apparatus detects a stream line from a pattern signal (S1), sets a stream line coordinate system determined by the stream line (S2), and calculates an attribute of the pattern feature based on the stream line coordinate system (S3). |
