Stabilizing Role of a Curvature Correction to Line Tension

SIAM Journal on Applied Mathematics, 2008
We study the effects that a curvature correction to the line tension has on the equilibrium and stability of liquid droplets laid upon a rigid substrate. In the simple case of cylindric liquid bridges we prove that even a tiny curvature correction prevents the onset of wildly oscillating perturbations that would make the contact line unstable if a ...

Lines of Curvature for Polyp Detection in Virtual Colonoscopy

IEEE Transactions on Visualization and Computer Graphics, 2006
Computer-aided diagnosis (CAD) is a helpful addition to laborious visual inspection for preselection of suspected colonic polyps in virtual colonoscopy. Most of the previous work on automatic polyp detection makes use of indicators based on the scalar curvature of the colon wall and can result in many false-positive detections. Our work tries to reduce

Umbilics and Lines of Curvature

2009
An umbilic is a point on a surface where all normal curvatures are equal in all directions, and hence principal directions are indeterminate. Thus the orthogonal net of lines of curvature, which is described in Sect. 3.4, becomes singular at an umbilic. An obvious example of a surface consisting entirely of umbilical points is the sphere.

*Lines of Curvature

2011
In this section, I will discuss lines of curvature. A curve x(t) is said to be a line of curvature if $$\frac{\mathrm{d}\mathbf{x}(t)} {\mathrm{d}t} = \mathbf{v}(t)\text{, where}$$ (10.1)

Tripartite Line Tracks Qualitative Curvature Information

2003
We present a qualitative shape description which has previously been proven to be useful for object categorisation. The description is based on a set of shape primitives which we will restrict to a new subset of relations representing stylised curvature information.
