A new hierarchical approach for the recognition of unconstrained handwritten numerals is proposed. In order to obtain a reliable skeleton of the observed character, some preprocessing operations including smoothing, noise removal, normalization, and a thinning process are first applied to each character. Then, some interesting feature points are extracted from this reliable skeleton of the character. In the first stage of preclassification, a set of structural features named four-zone codes is…

Heuristic approach to handwritten numeral recognition
The method is designed to read the worst written numerals, where structural differences among numerals are investigated and the extracted heuristic features are: the order of interesting points, numbers of endpoints, forkpoints, crosspoints, breakpoints and subpieces, the slope-change of each subpiece, the orientation and the length of eachSubpiece.
