OCR Recognition System Using Feed Forward and Back Propagation Neural Network

Abstract

In this paper, a for Tamil, English characters, and digits recognition is proposed by applying algorithms to the network. The can effectively recognize various English, Tamil characters and digits with good recognition rates. A feed forward, Back Propagation, and classifying algorithm is capable of reducing the number of neurons and increasing recognition rates for the fixed number of output neurons. An Artificial Neural Network (ANN), often just called a neural network (NN), is a mathematical model or computational model based on biological networks. It consists of an interconnected group of artificial neurons and processes information using a connectionist approach to computation. In most cases an ANN is an adaptive system that changes its structure based on external or internal information that flows through the during the learning phase. In more practical terms networks are non-linear statistical data modeling tools. They can be used to model complex relationships between inputs and outputs or to find patterns in data. The simulations have indicated that the can effectively recognize various English, Tamil characters and digits with good recognition rates.
