local curvature

The local curvature of the discrete contour, which characterizes the bending of a contour associated with a direction, is defined using the center of the inscribed circle of the triangle derived from three consecutive contour nodes.

探讨了深度凹陷区域的分割，用离散轮廓上顺序3点所成三角形内切圆圆心来定义离散轮廓的曲率，该曲率既能反映轮廓的弯曲程度，又具有合理的方向。
