Paper Abstract

In this paper, we presented an approach for detection of perceptually salient curvature extrema on surfaces approximated by dense triangles. Based on the properties of B-spline or NURBS, we use data points instead of scattered points (control points)and their principal and mean curvatures and explore “area degenerating” method to detect the salient curvature features.. This paper demonstrates the advantages of the proposed method by comparison with existing algorithms.
