چکیده

The problems of character recognition are today mainly due to imperfect thresholding and segmentation In this paper a new ap proach to text recognition is presented which attempts to avoid these problems by working directly on grey level images and treating an en tire word at the time The features are found from the grey levels of the image and a hidden Markov model is de ned for each character During recognition the most probable combination of models is found for each word by the use of dynamic programming
