Abstract

To improve overall separation and classification performance handwritten numeral strings, we have to deal with double - which occur particularly for some combinations of digits. We strategy to separate single- and double-touching numerical proposed technique includes: using two-cut links to deal with problems; using weighted geometric-property measures to rank two-cut links; and using a rejection scheme to reject poor ranking and recognition stages. Two-cut link pairs that join high-curvature points in inner contour(s) to those in the are considered when all one-cut links that join the upper and external contours fail to separate them. All combinations of links are ranked according to weighted geometric-property top links are chosen and tested by the recognition system. results on the National Institute of Standards and Technology that our system for solving both single- and double-touching compares favorably with the other techniques tested.
