Curve matching for open 2D curves
Pattern Recognition Letters, 2009We present a curve matching framework for planar open curves under similarity transform based on a new scale invariant signature. The signature is derived from the concept of integral of unsigned curvatures. If one input curve as a whole can be aligned with some part in the second curve then the algorithm will find the requisite starting and end ...

Casting curved shadows on curved surfaces
Proceedings of the 5th annual conference on Computer graphics and interactive techniques, 1978Shadowing has historically been used to increase the intelligibility of scenes in electron microscopy and aerial survey. Various methods have been published for the determination of shadows in computer synthesized scenes. The display of shadows may make the shape and relative position of objects in such scenes more comprehensible; it is a technique ...

The Contract Curve and the Production Possibility Curve
Journal of Political Economy, 1971The purpose of this paper is to show that the assumption of linear homogeneity of the neoclassical production function only leads to concavity at the two ends of the production contract curve. The other part of the curve may be either convex or concave to the diagonal, depending on the changes in the elasticities of substitution of factors of ...

In this chapter, we associate two scalar functions, its curvature and torsion, to any curve in ℝ3. The curvature measures the extent to which a curve is not contained in a straight line (so that straight lines have zero curvature), and the torsion measures the extent to which a curve is not contained in a plane (so that plane curves have zero torsion).
