Force-driven optimization for correspondence establishment
Correspondence establishment has been a difficult problem in machine vision. In this paper, we present an optimization technique for the task. The geometric constraints to the solution arc formulated as forces, which are combined to provide clue for mapping between two sets of points such that the geometric constraints are best satisfied. The strong point of this method is that it is easy to integrate several sources of information to obtain a solution while keeping the decision simple, and does not suffer from the uncontrollable flexibility as in active contour models. We illustrate the method with the problem of establishing correspondence between parallel curves.
