Paper Abstract
This paper presents a method for detecting corner points on 3D space curves. It is an extension of a previous work of distance accumulation for detecting corner points on 2D planar curves.6•7 A quantitative measure is proposed to define the "cornerness" of a 3D curve at a curve point, which has the advantage of being more stable and causing much less shape distortion than the traditional smoothing methods. In particular, this measure is invariant to scale, an attractive property for corner detection. Strategies are presented for reliable maximum selection. Experimental results with simulated data shows that the robustness and accuracy of the cornerness method.
Keywords - Corner detection, curvature, distance accumulation, maxima selection, curve representation, 3D curves.
