A complete OCR for printed Tamil text

A Neural Network approach is proposed to build an automatic off-line handwritten Tamil character recognition system. We have used a Back Propagation Network (BPN) as a character recognizer. Once trained, the network has a very fast response time. However, the learning phase of this recognizer is a relatively difficult task in this application. The input image of the handwritten character is given as input to the BPN and the character most closely resembling the block of pixels is given as output. This system uses a three layer backpropagation neural network .
