An adaptive smoothing approach for fitting digital planar curves with line segments and circular arcs

摘要

This paper presents a new method to produce a representation of a digital curve. The method first finds a curvature representation for a Gaussian-filtered curve. The curvature representation is then smoothed by using the adaptive smoothing technique. Finally, we segment the digital curve and fit each segment with a line segment or a circular arc based on the smoothed curvature representation. Experimental results show the applicability and efficiency of the proposed method.
