Abstract：A method based on geometric moments and dominant points is proposed. Algorithm for detecting dominant points could keep the original contour feature as much as possible, but the number of remain vertexes is not controllable. On the contrary, the method based on geometric moments can reduce the amount of vertexes to any number, but it makes the fitting result get into local optimum. Thus, a new method is introduced which integrates the two algorithms. In this way, most closed curves can be fitted to polygons with specified number of vertexes in a global optimal way.
