Elastica and computer vision. (English) Zbl 0798.53003
Bajaj, Chandrajit L. (ed.), Algebraic geometry and its applications. Collections of papers from Shreeram S. Abhyankar’s 60th birthday conference held at Purdue University, West Lafayette, IN, USA, June 1-4, 1990. New York: Springer-Verlag. 491-506 (1994).
First the author describes a method to reconstruct the hidden parts of contour lines (edges) by plane elastic curves in a 2D image that comes from 3D geometry. Second, plane elastic curves are expressed in terms of theta functions.
For the entire collection see [Zbl 0788.00050].
