The dynamic nature of blood flow during hyperthermia therapy has made the control of minimum tumor temperature a difficult task. This paper presents initial studies of a novel approach to closed-loop control of local minimum tissue temperatures utilizing a newly developed estimation algorithm for use with conductive interstitial heating systems. The local minimum tumor temperature is explicitly...
We study a narrow band type algorithm to solve a discrete formulation of the convex relaxation of energy functionals with total variation regularization and non convex data terms. We prove that this algorithm converges to a local minimum of the original non linear optimization problem. We illustrate the algorithm with experiments for disparity computation in stereo and a multi-label segmentatio...
The minimum spanning tree pyramid is a hierarchical image segmentation method. We study it’s properties and the regions it produces. We show the similarity with the watershed transform and present the method in a domain in which this is easy to understand. For this, a short overview of both methods is given. Catchment basins are contracted before their neighbouring local maximas. Smooth regions...
