On Detection of Prominent Point Using B-Spline Model
摘要
Abstract
A method to detect prominent points of digital curves is presented. It introduces a B-spline model to approximate the original curve so that the curvatures can be accurately estimated with the analytical expression and then the prominent points can be determined from the curvature distribution. Moreover the B-spline approximation makes its noise insensitive to detect the prominent points, due to its smoothness in the curve fitting which does not have shrinkage effects like Gaussian function convolution. Experimental results show the validity of this method.关键词
