Optical character recognition (OCR) is process of classification of optical patterns contained in a digital image. The character recognition is achieved through pre-processing, segmentation and feature extraction. The paper starts with a brief background and history of OCR systems. The different techniques of OCR systems such as Optical Scanning, Location Segmentation, Pre-processing, Segmentation and Feature Extraction, Recognition the character are used. The different applications of OCR systems are highlighted next followed by the current status of the OCR systems. Finally, the future of the OCR systems is presented.
