| 摘 要： | 提出了一种新的圆孤逼近轮廓曲线进行目标匹配的方法-最大比率法。曲线上两点之间的圆弧和曲线夹成的面积与对应扇形的比值随曲线上点的曲率的变化而变化。通过设置一个阈值算法可以检测曲率的较大的特征点用于圆弧逼近匹配。

| Abstract: | This paper presents a novel method of arc approximating for shape matching-Max Ratio. The main idea is that the arcs between two points on a curve and radiuses make a sector, and the ratio of the area between arc and curve to the area of sector will change according to curvature changes on the curve. With an appropriate threshold algorithm, characteristic points belonging to high curvature parts of the curve can be determined. |
