PATTERN FEATURE DETECTION SYSTEM |
摘要 |
A pattern feature detection system which detects the slope at any point of a line pattern to be identified to determine whether the pattern is monotonously increasing or monotonously decreasing at that point, thereby dividing the pattern into line segments at positions where the sign of the monotonousness changes, that is, at positions of zero slope.
