In this paper, we describe an efficient image-based approach to computing and shading
visual hulls from silhouette image data. Our algorithm takes advantage of epipolar geometry …

Abstract Systems and techniques to implement augmented virtual environments. In one
implementation, the technique includes: generating a three dimensional (3D) model of an …

Private information retrieval (PIR) protocols allow a user to retrieve a data item from a
database while hiding the identity of the item being retrieved. Specifically, in information …

This paper presents a framework to reconstruct a scene captured in multiple camera views
based on a prior model of the scene geometry. The framework is applied to the capture of …

Steady growth in the speeds of network links and graphics accelerator cards has brought
increasing interest in streaming transmission of three-dimensional data sets. We …

We present an approach for modeling and rendering a dynamic, real-world event from an
arbitrary viewpoint, and at any time, using images captured from multiple video cameras …

This paper proposes a new scheme for multi-image projective reconstruction based on a
projective grid space. The projective grid space is defined by two basis views and the …

This paper introduces a stereo vision system to automatically generate 3D models of real
objects. 3D model generation is based on the merging of multiview range images obtained …

A method and a system of generating a video image sequence. According to one
embodiment, the method includes positioning a plurality of camera systems relative to a …

We present a method to automatically extract spatio-temporal descriptions of moving objects
from synchronized and calibrated multi-view sequences. The object is modeled by a time …
