Realistic Reflections and Refractions on Graphics Hardware with Hybrid Rendering and Layered Environment Maps
We introduce hybrid rendering, a scheme that dynamically ray traces the local geometry of reflective and refractive objects, but approximates more distant geometry by hardwaresupp...

Visual Servoing for Automatic and Uncalibrated Needle Placement for Percutaneous Procedures
This paper presents a new approach to image-based guidance of a needle or surgical tool during percutaneous procedures. The method is based on visual servoing. It requires no prio...
