The Effect of Viewing a Self-Avatar on Distance Judgments in an HMD-Based Virtual Environment
Few HMD-based virtual environment systems display a rendering of the user's own body. Subjectively, this often leads to a sense of disembodiment in the virtual world. We expl...

Compressive sensing with local geometric features
We propose a framework for compressive sensing of images with local geometric features. Specifically, let x ∈ RN be an N-pixel image, where each pixel p has value xp. The image...

Use of rational numbers in the design of robust geometric primitives for three-dimensional spatial database systems
A necessary step in the implementation of three-dimensional spatial data types for spatial database systems and GIS is the development of robust geometric primitives. The authors ...
