摘要
Abstract
On the basic of contour extraction of fragments, a novel contour matching algorithm was present, which is a curve matching framework for planar open curves under similarity trans-form based on a new scale invariant signature The signature is derived from the concept of integral of unsigned curvatures The main idea behind this method was firstly to utilize integral of unsigned curvatures to calculate point wise curvatures, and the feature points were selected The segments consist of the feature points The Hausdorff distance between feature segments indicated their math degree If the Hausdorff distance is less than the given tolerance, the contour is matched The contributions of the paper are the new signature as well as faster algorithms for matching open 2D curves The method proves to be effective by realistic experiments关键词
