Abstract

A new boundary contour extraction algorithm based on curve evolution model and ant colony algorithm is proposed in this paper Firstly, ant colony algorithm is used to find the optima of snake points for rapidly converging near image edge Then the interpolation algorithm is applied to gaining the object's rough contour that is used as the initial zero level set The accurate contour can be obtained by the curve evolution method Experimental results are given to demonstrate the feasibility of the proposed method in extracting contour from the blurred edge and high-noise images.
