In this paper, we introduce a new simple proposal for deletion of ellipse enclosing character in documentary images. In this proposal, ellipse enclosing character is labeled, parameters for the center point of an ellipse are found using circumscribing rectangle of the labeled ellipse, the parameters for half-lengths of the major axis and minor axis are determined by finding the farthest point and the nearest point on labeled ellipse from the center point, the ellipse orientation is determined by finding the angle between major axis and horizontal direction, then the ellipse is modeled using these parameters. Ellipse detection is conducted counting the number of pixels on the ellipse model. Finally, ellipse enclosing characters are distinguished from characters having an ellipse shape. Results of the experiments using appropriate images showed the effectiveness of our proposal. The sections that follow detail problems overcome and our projected work.
