ENGLISH ALPHABET RECOGNITION USING CHAIN CODE AND LCS

Since several decades OCR system is getting more and more useful in daily life for various purposes. Many researches have been done on many types of characters by using different approaches. Howeververy little investigation have been performed by chain code base approach. In this paper, a new kind of algorithm, based on that chain code along with another significant characteristic, number of vertices(end or junction point) and edges (chain code, from one vertex to another) existing in each alphabet has been used to identify English Capital Characters. We have built a technique that is independent of size and many styles of input characters. Experimental results show relatively high accuracy.
