Kinky tomographic reconstruction

We address the issue of how to make decisions about the degree of smoothness demanded of a flexible contour used to model the boundary of a 2D object. We demonstrate the use of a Bayesian approach to set the strength of the smoothness prior for a tomographic reconstruction problem. The Akaike Information Criterion is used to determine whether to allow a kink in the contour.

Keywords: active contours, deformable geometry, Akaike Information Criterion, Bayesian analysis, model-order selection
