【摘要】 在计算机视觉中，平面曲线的透视不变性描述有着非常重要的意义．为了用透视投影不变量实现复杂平面曲线的准确描述，本文提出了平面曲线透视不变性分段的概念和用零曲率点和尖点实现平面曲线透视不变分段的方法，并用实验证明了这种方法的正确性和可靠性．更多还原

【Abstract】 The description of planar curves is very important in computer vision.In order to describe the shapes of complex planar curves accurately, this paper pre sents a concept of perspective invariance segmentation of planar curves, and gives amethod to implement perspective invariance segmentation of planar curves using ze ro curvature and corner points. The experimental results have proved the efficiencyand reliability of the method.更多还原
