| Abstract: | This paper proposes the method based on projection to clip rectangular window three times by Bezier Curve. Through horizontal and vertical projections to the curve, it could be judged whether the curve is in rectangular window or not. The method proposed in the paper is simple and the process is comparatively quick. |
