In this thesis, we describe a statistical method for 3D object detection. In this method, we decompose the 3D geometry of each object into a small number of viewpoints. For each viewpoint, we construct a decision rule that determines if the object is present at that specific orientation. Each decision rule uses the statistics of both object appearance and(More)
Recent years have seen exciting advances in Computer Assisted Surgery (CAS). CAS systems are currently in use which provide data to the surgeon, provide passive feedback and motion constraint, and even automate parts of the surgery by manipulating cutters and endoscopic cameras. For most of these systems, accurate registration between the patient’s anatomy(More)
Existing featureless image mosaicing techniques do not pay enough attention to the robustness of the image registration process, and are not able to combine multiple video sequences into an integrated panoramic view. These problems have certainly restricted applications of the existing methods for large-scale panorama composition, video content overview and(More)
We have begun development of a telerobotic system to replace a human camera operator in endoscopic surgical procedures. The system will consist oj‘ U remote centeroFm:motion manipulator holding the endoscope; U computer workstation supporting image processing, graphicx, manipulator control, and other junctions; and a variety oj‘ man-machine interfirces(More)
This paper presents a framework for augmented reality. Head tracking is accomplished using a head-mounted camera, which uses an optical flow based algorithm to track patterns on the ceiling. The position and orientation of the ceiling need not be known a priori, and the necessary calibration, except for radial lens distortion, can be performed on the fly(More)
he goal of this work is to develop a new T generation of “intelligent” surgical systems that can work cooperatively with a human surgeon to off-load routine tasks, reduce the number of people needed in the operating room, and provide new capabilities that complement the surgeon’s own skills. An underlying premise of this work is that machine capabilities(More)
