Text detection and Character recognition from the image has been one of the most interesting and challenging research areas in field of pattern recognition, artificial intelligence, machine vision and image processing in the recent years. There are basically four steps that include preprocessing, feature extraction, candidate's selection, and desired character recognition to develop any of the character recognition system.
Optical character recognition is the technique to convert text from the image into computer or machine readable form. Like intelligent character recognition (ICR) one character is taken at a time to make it editable by the machine. There are several approaches for developing the OCR system but in this review we emphasis on OCR using artificial neural network trained by back propagation algorithm and fuzzy logic.
