Optical character recognition (OCR) has been a topic of great interest for many years. It is a system that permits us to convert various types of documents into machine encoded/computer-readable text. It consist of steps like image acquisition, pre- processing, segmentation, feature extraction, etc. The purpose of this work is to summarize the researches performed in the OCR field. It provides an overview of different aspects of OCR and discusses corresponding proposals aimed at resolving problems of OCR. A practical OCR problem is also investigated.
