Character Recognition Based on DTW-Radon

Abstract—The paper presents a method for isolated offline character recognition using radon features. The key characteristic of the method is to use DTW algorithm to match corresponding pairs of radon histograms at every projecting angle. Thanks to DTW, it avoids compressing feature matrix into a single vector which may miss information. Comparison has been made with the state–of–the–art of shape descriptors over several different character as well as numeral datasets from different scripts. Keywords-Character Recognition; Radon Transform; DTW.
