Kinky tomographic reconstruction
Kenneth M. Hanson, Roger Bilisoly, Gregory Scott Cunningham · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1996
We address the issue of how to make decision 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.
