In this paper, an automatic and efficient algorithm for outline capture of character images, stored as bitmap, is presented. This method is well suited for characters of non-Roman languages like Arabic, Japanese, Urdu, Persian, etc. Contemporary word processing systems store shapes of the characters in terms of their outlines, and outlines are expressed as cubic Bezier curves. The process of capturing outlines includes steps: detection of boundary, finding Corner Points and Break Points and fitting the curve. The work done in this paper, fully automate the above process and produces optimal results.
