Abstract

This paper evaluates and compares ‘confident’ adaptive algorithms with other adaptive and non-adaptive algorithms that implement the estimation of motion, focusing on the finite element method as a framework for the development of techniques. The finite element approach has many advantages which include a rigorous mathematical formulation, conceptual simplicity and ease of implementation via well-established finite element procedures in comparison to finite volume or finite difference techniques. The finite element techniques are implemented through a variety of grid discretisations, with results presented and compared.
