Odia-Conjunct character recogntion using evolutionary algorithm
Keywords:Odia language, Optical Character Recognition (OCR), Artificial Neural Network (ANN), Genetic Algorithm (GA)
AbstractMost efforts have been devoted to the recognition of isolated printed and handwritten Odia basic fonts; however recognition of complex conjunct characters is still an area of active research. This paper presents an effective text recognition scheme for Odia conjunct characters. The shape of conjunct characters is inherently complex and imposes great challenges to the researcher group of Odia Optical Character Recognition. The weightiness of this work lies on design and development of an optimized classification method by combining the back-propagation neural network with genetic algorithm to achieve both the training swiftness and accuracy for recognition. We compare the back-propagation neural network (BPNN) and genetic algorithm optimized in artificial neural network (GAONN) and found that GAONN produces more promising result then BPNN.Â Â Â Finally we show that the method yields high accuracy rate and depict the most promising research guidelines in this field.
