S.M. Ali and H. I. A Al- Hashimi Remote Sensing Unit, College of Science, University of Baghdad IRAQ, BAGHDAD, AL-JADERYIA Received: 5/8/2000 Accepted: 9/1/2001

ABSTRACT

    New isolation and extraction techniques, based on the chain coding and projection methods, to separated typed and handwriting characters from a text’s image are introduced. A number of matching techniques are developed and used to achieve the character recognition problem; i.e. Cross- correlation coefficient, several order invariant moments, projection moments (introduced here), and, Co - Occurrence matrices techniques.
