Abstract

The computer plays vital role in all industries. The dependence on computers keeps on increasing every day. The digitization of information transfer between machine and men helps to make the paper-free society. The Optical Character Recognition (OCR) and its applications help us to make the digital world. In this paper, we review the various OCR approaches for recognizing the characters from different images. We reviewed the papers of OCR applied in recognizing texts in natural scenes, traffic signs and energy meter reading. We have initiated our presentation with handwritten text recognition using neural network to understand the process of OCR.
