Performance Scrutiny of Thinning Algorithms on Printed Gujarati Characters and Handwritten Numerals

We analyze the behavior of most common thinning algorithms on printed Gujarati text and handwritten numerals. We are focusing mostly on two types of algorithms: The first is serial thinning and second is parallel thinning. Thinning is more crucial when we focusing on structural feature-based character recognition. Thinned character reduced complication of the shape of the character. This analysis focuses on the actual result we get after applying serial and parallel thinning algorithms. Total five algorithms are used for experiments and applied on small, medium, big size of character data and on skewed character data. The results are useful where we designing classifiers for Gujarati text.
