Method for optical recognition of alphanumeric characters |
摘要 |
<p>The method involves storing polygonal outer contours and inner contours of reference characters and their relative geometrical positions. An outer contour and inner contours of a character to be recognized are optically scanned. The character to be recognized is compared to the reference characters by shifting a character curve of an outer curve and reference curves of the outer contours.</p> |
