Abstract We are proposing a segmentation technique for the learning of the two Bangla digits incorporating the grid method, the regional search method, the feature extraction method, and the counterpropagation neural network. We emphasized the recognition of the two Bangla digits one and nine since these two digits look similar. The experimental result shows an overall increased rate of recognition for Bangla one and nine.

1. Introduction Bangla is a language spoken by the people of Bangladesh and the people of the state of West Bengal in India. Bangla character recognition using different approaches has become a field of interest in the last few years. In spite of its interests, the progress in this field has not been very fast. So far, only a limited amount of work has been done successfully with Bangle character recognition due to its complexity. Literature survey on the Bangla digit recognition techniques revealed that the simulation results of all the approaches were suffering from the low recognition rates of Bangla one and nine since both of them look similar. Therefore, we paid special attention on the recognition of Bangla digit one and nine. Earlier work of Rahman et al.9, Syeed et al.10, Mollah and Talukder11, and Rahman et al.12 inspired us to initiate the work in this area. The technique that was formulated here for the improvement of the recognition incorporated the
