Abstract
A new method of calculating discrete curvature on digital curves is proposed based on Taylor's theorem. The method first determines the region of support for each point based on its local properties, then computes its curvature absolute value according to the vector accumulation. The vector is formed by the point and the middle point of a moving chord. It can be applied to both planar and space curves. Experimental results with simulated and real images show that this method is simple and robust, and can represent the features of digital curves.
