Texture sprites: texture elements splatted on surfaces
We present a new interactive method to texture complex geometries at very high resolution, while using little memory and without the need for a global planar parameterization. We ...

Chaotic Maps as Parsimonious Bit Error Models of Wireless Channels
Abstract—The error patterns of a wireless digital communication channel can be described by looking at consecutively correct or erroneous bits (runs and bursts) and at the distri...

Opacity light fields: interactive rendering of surface light fields with view-dependent opacity
We present new hardware-accelerated techniques for rendering surface light fields with opacity hulls that allow for interactive visualization of objects that have complex reflec...

Satisfiability and Resiliency in Workflow Systems
We propose the role-and-relation-based access control (R2 BAC) model for workflow systems. In R2 BAC, in addition to a user's role memberships, the user's relationships w...

Object Tracking with Bayesian Estimation of Dynamic Layer Representations
Decomposing video frames into coherent two-dimensional motion layers is a powerful method for representing videos. Such a representation provides an intermediate description that e...
