Some new heuristics for thinning binary handprinted characters for OCR
Fred W. M. Stentiford, Rudolf G. Mortimer · IEEE Transactions on Systems Man and Cybernetics · 1983
A standard thinning algorithm which consists of a matrix matching scheme used in conjunction with a connectivity measure is briefly described. Several new heuristics are introduced to obviate some of the common shortcomings of thinning algorithms when applied to handprinted data.
