Abstract This paper proposes a new method of contour extraction using active contour models for the purpose of image structuring. Active Contour Models, such as “snakes,” are based on energy minimization, which takes a great deal of computational time. In the proposed method, the active contour models consist of sampled contour points, and each sampled contour point is guided and moves in parallel by pressure exerted perpendicularly to the contour, attraction between neighbor boundary points, and repulsion from edge. Since each contour point is independently guided by a resultant force, the proposed method has the following characteristics: noise tolerance; parallel execution; and low computational cost. Experimental results on real pictures show the effectiveness of this method.
