An efficient collision detection algorithm using range data for walk-through systems
We present a simple, but efficient view collision detection method for the walk-through system. The basic idea is to check if the current view position intersects with the range d...

Stratified Learning of Local Anatomical Context for Lung Nodules in CT Images
The automatic detection of lung nodules attached to other pulmonary structures is a useful yet challenging task in lung CAD systems. In this paper, we propose a stratified statist...

Feature Detection with Automatic Scale Selection
The fact that objects in the world appear in different ways depending on the scale of observation has important implications if one aims at describing them. It shows that the not...
