A Finite Element Method for Deformable Models
P. Karaolani, G. D. Sullivan, Keith D. Baker, M. J. Baines · 1989
Deformable models of elastic structures have been proposed for use in image analysis. Previous work has used a variational approach, based on the Euler-Lagrange theory. In this paper an alternative mathematical treatment is introduced, based on a direct minimisation of the underlying energy integral using the Finite Element Method. The method is outlined and demonstrated, and its principal advantages for modelbased image interpretation are explained.
