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.
