Summary This paper presents a comparative analysis of two projection based feature extraction techniques namely Radon and fan-beam. Fan-beam technique is a variation of Radon transform and usually used in tomography. In this work, Radon and fan-beam projections are used to compute feature vectors of Bangla characters. Extracted features are simulated for recognition and the recognition rates are compared for both of the methods.
