ROBUST INCORPORATION OF ANATOMICAL PRIORS INTO LIMITED VIEW TOMOGRAPHY USING MULTIPLE CLUSTER MODELLING OF THE JOINT HISTOGRAM
We apply the joint entropy prior to limited view transmission tomography and demonstrate its sensitivity to local optima. We propose to increase robustness by modelling the joint histogram as the sum of a limited number of bivariate clusters. The method is illustrated for the case of Gaussian distri...
