An Information Fusion Approach for Multiview Feature Tracking
We propose an information fusion approach to tracking objects from different viewpoints that can detect and recover from tracking failures. We introduce a reliability measure that...

Modeling Clinical Tumors to Create Reference Data for Tumor Volume Measurement
Abstract. Expanding on our previously developed method for inserting synthetic objects into clinical computed tomography (CT) data, we model a set of eight clinical tumors that spa...

Accelerating shadow rays using volumetric occluders and modified kd-tree traversal
Monte Carlo ray tracing remains a simple and elegant method for generating robust shadows. This approach, however, is often hampered by the time needed to evaluate the numerous sh...

Simultaneous photometric invariance and shape recovery
In this paper we identify the constraints under which the generally ill-posed problem of the simultaneous recovery of surface shape and its photometric invariants can be rendered ...
