A Relative Study on OCR System for Devanagri Character Recognition Feature Extraction Techniques

The script 'Devanagari' is used in many Indian languages. Recognition of handwritten characters of Devanagari character set is an important and complex area of research. The work done for the recognition of Devanagari handwritten script is very small in books (even though there is the existence of) it is being used by millions people in India and abroad and it has numerous applications. The feature extraction method(s) used to recognize hand-written characters play an important role in many applications. In this paper, we will discuss various feature extraction method techniques used by the researchers and scholars in optical character recognition process. After reading this we will able to understand what is feature extraction, steps involve in recognition process and how to use and modify existing techniques to improve recognition rate, accuracy and overall performance.
