Estimation of Discontinuous Displacement Vector Fields with the Minimum Description Length Criterion.

Abstract

A new noniterative approach to determine displacement vector fields with discontinuities is described. In order to overcome the limitations of current methods, the problem is regarded as a general modelling problem. From this point of view the imaging field consists of a set of regions with common properties and their boundaries. The strategy proposed is an analysis of consistency of the displacement estimators between different levels of regularization. A fully regularized family of model based displacement vector fields is constructed by successive smoothing and subsampling. By measuring the difference in description length the compatibility between different levels of regularization is measured. This gives local but noisy evidence of possible model boundaries at multiple scales.
