Understanding camera trade-offs through a Bayesian analysis of light field projections - A revision
(2008-07-28)
Computer vision has traditionally focused on extracting structure,such as depth, from images acquired using thin-lens or pinholeoptics. The development of computational imaging is broadening thisscope; a variety of ...
Event Order Abstraction for Parametric Real-Time System Verification
(2008-07-28)
We present a new abstraction technique, event order abstraction (EOA), for parametric safety verification of real-time systems in which ``correct orderings of events'' needed for system correctness are maintained by timing ...
The SoftPHY Abstraction: from Packets to Symbols in Wireless Network Design
(2008-06-03)
At ever-increasing rates, we are using wireless systems to communicatewith others and retrieve content of interest to us. Current wirelesstechnologies such as WiFi or Zigbee use forward error correction todrive bit error ...
Interactive Simulation of Stylized Human Locomotion
(2008-08-01)
Animating natural human motion in dynamic environments is difficult because of complex geometric and physical interactions. Simulation provides an automatic solution to parts of this problem, but it needs control systems ...
Programmable Self-Assembly: Constructing Global Shape using Biologically-inspire
(2001-06-01)
In this thesis I present a language for instructing a sheet of identically-programmed, flexible, autonomous agents (``cells'') to assemble themselves into a predetermined global shape, using local interactions. The ...
Feature Point Detection and Curve Approximation for Early Processing of Freehand Sketches
(2001-05-01)
Freehand sketching is both a natural and crucial part of design, yet is unsupported by current design automation software. We are working to combine the flexibility and ease of use of paper and pencil with the processing ...
2D-3D Rigid-Body Registration of X-Ray Fluoroscopy and CT Images
(2001-08-01)
The registration of pre-operative volumetric datasets to intra- operative two-dimensional images provides an improved way of verifying patient position and medical instrument loca- tion. In applications from orthopedics ...
Generating Communications Systems Through Shared Context
(2002-01-01)
In a distributed model of intelligence, peer components need to communicate with one another. I present a system which enables two agents connected by a thick twisted bundle of wires to bootstrap a simple communication ...
Surface Reflectance Recognition and Real-World Illumination Statistics
(2002-10-01)
Humans distinguish materials such as metal, plastic, and paper effortlessly at a glance. Traditional computer vision systems cannot solve this problem at all. Recognizing surface reflectance properties from a single ...
Achieving Real-Time Mode Estimation through Offline Compilation
(2002-10-22)
As exploration of our solar system and outerspace move into the future, spacecraft are being developed to venture on increasingly challenging missions with bold objectives. The spacecraft tasked with completing these ...
