We prove that the maximum number of intersecting pairs spheres between two sets of polydisperse sphere packings is linear in the worst case. This observation is the basis for a new collision detection algorithm. Our new approach guarantees a linear worst case running time for arbitrary 3D objects. Additionally, we present a parallelization of our new algorithm that runs in constant time, even i...

There seems to be a great deal of confusion about the meaning of these developments. It seems wise to go over the facts and see if we can separate the subjective components from the objective components. The purpose of this document is to try to put our evaluation of the new formats on a rational basis. This will not, by itself, answer all our questions: there is undoubtedly a subjective and pr...

In multi-atlas based segmentation, a target image is segmented by registering multiple atlas images to this target image and propagating the corresponding atlas segmentations. These propagated segmentations are then combined into a single segmentation in a process called label fusion. Multi-atlas based segmentation is a segmentation method that allows fully automatic segmentation of image popul...
