Local diffusion regularization method for optical tomography reconstruction by using robust statistics

Opt Lett. 2005 Sep 15;30(18):2439-41. doi: 10.1364/ol.30.002439.

Abstract

We formulate a solution to the diffuse optical tomography (DOT) inverse problem as the minimization of an energy functional of the solution and the data. For the solution prior we introduce a local diffusion regularization potential with a threshold based on robust statistics (the Hubert function). We compare results on simulated data for the Hubert function and two other standard regularization functionals, Tikhonov and total variation.
