In this paper, we propose an original tree matching algorithm for intra-patient hepatic vascular system registration. The vascular systems are segmented from CT-Scan images acquired at different time, and then modeled as trees. The goal of this algorithm is to find common bifurcations (nodes) and vessels (edges) in both trees. Starting from the tree root,(More)
In this paper, a new approach to the discretization of n-dimensional Euclidean figures is studied: the discretization of a compact Euclidean set K is a discrete set S whose Hausdorff distance to K is minimal; in particular such a discretization depends on the choice of a metric in the Euclidean space, for example the Euclidean or a chamfer distance. We call(More)
