✦ Synopsis

In this paper, we propose an adaptive method for the polygonal approximation of a digitized curve. Instead of setting a ΓΏxed length of support region in advance, the new method will compute the suitable length of support region for each point to ΓΏnd the best approximated curvature. The dominant points are identiΓΏed as the points with local maximum curvatures. In addition, the break point detection is conducted to reduce the computations. The experimental results show that the proposed method can approximate the curves e ectively.

An efficient method for dominant point detection is proposed in this paper. The region of support for each point on curve is determined using bending value. The points with local maximum smoothing bending value can be located as the dominant points on the curve. The proposed algorithm needs no input
