MULTI-SCALE RECOGNIZER FOR HAND DRAWN STROKES |
摘要 |
MULTI-SCALE RECOGNIZER FOR HAND DRAWN STROKES A known hand drawn stroke is serially sampled at different scales by n angle filters to provide n filtered known strokes at n different scales. An unknown hand drawn stroke is sampled in a like manner to provide n filtered unknown strokes at n different scales. Filtered unknown strokes are compared with filtered known strokes. If there is a comparison within predetermined limits at any scale, the unknown hand drawn stroke is recognized as being the same as the known hand drawn stroke.
