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 ... -
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 ... -
ADAM: A Decentralized Parallel Computer Architecture Featuring Fast Thread and Data Migration and a Uniform Hardware Abstraction
(2002-06-01)The furious pace of Moore's Law is driving computer architecture into a realm where the the speed of light is the dominant factor in system latencies. The number of clock cycles to span a chip are increasing, while the ... -
An Analog VLSI Chip for Estimating the Focus of Expansion
(1996-08-21)For applications involving the control of moving vehicles, the recovery of relative motion between a camera and its environment is of high utility. This thesis describes the design and testing of a real-time analog ... -
Automatically Recovering Geometry and Texture from Large Sets of Calibrated Images
(1999-10-22)Three-dimensional models which contain both geometry and texture have numerous applications such as urban planning, physical simulation, and virtual environments. A major focus of computer vision (and recently graphics) ... -
BioJADE: A Design and Simulation Tool for Synthetic Biological Systems
(2004-05-28)The next generations of both biological engineering and computer engineering demand that control be exerted at the molecular level. Creating, characterizing and controlling synthetic biological systems may provide us ... -
A Biological Model of Object Recognition with Feature Learning
(2003-06-01)Previous biological models of object recognition in cortex have been evaluated using idealized scenes and have hard-coded features, such as the HMAX model by Riesenhuber and Poggio [10]. Because HMAX uses the same set ... -
Building Grounded Abstractions for Artificial Intelligence Programming
(2004-06-16)Most Artificial Intelligence (AI) work can be characterized as either ``high-level'' (e.g., logical, symbolic) or ``low-level'' (e.g., connectionist networks, behavior-based robotics). Each approach suffers from particular ... -
Compact Representations for Fast Nonrigid Registration of Medical Images
(2003-07-04)We develop efficient techniques for the non-rigid registration of medical images by using representations that adapt to the anatomy found in such images. Images of anatomical structures typically have uniform intensity ... -
Design and Control of an Anthropomorphic Robotic Finger with Multi-point Tactile Sensation
(2001-05-01)The goal of this research is to develop the prototype of a tactile sensing platform for anthropomorphic manipulation research. We investigate this problem through the fabrication and simple control of a planar 2-DOF robotic ... -
Design and Evaluation of the Hamal Parallel Computer
(2002-12-05)Parallel shared-memory machines with hundreds or thousands of processor-memory nodes have been built; in the future we will see machines with millions or even billions of nodes. Associated with such large systems is a new ... -
Face Representation in Cortex: Studies Using a Simple and Not So Special Model
(2003-06-05)The face inversion effect has been widely documented as an effect of the uniqueness of face processing. Using a computational model, we show that the face inversion effect is a byproduct of expertise with respect to 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 ... -
Fluorescence Assay for Polymerase Arrival Rates
(2003-08-31)To engineer complex synthetic biological systems will require modular design, assembly, and characterization strategies. The RNA polymerase arrival rate (PAR) is defined to be the rate that RNA polymerases arrive at a ... -
Gait Analysis for Classification
(2003-06-26)This thesis describes a representation of gait appearance for the purpose of person identification and classification. This gait representation is based on simple localized image features such as moments extracted from ... -
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 ... -
Generative Temporal Planning with Complex Processes
(2004-05-18)Autonomous vehicles are increasingly being used in mission-critical applications, and robust methods are needed for controlling these inherently unreliable and complex systems. This thesis advocates the use of model-based ... -
Importance Sampling for Reinforcement Learning with Multiple Objectives
(2001-08-01)This thesis considers three complications that arise from applying reinforcement learning to a real-world application. In the process of using reinforcement learning to build an adaptive electronic market-maker, we find ... -
Improving Multi-class Text Classification with Naive Bayes
(2001-09-01)There are numerous text documents available in electronic form. More and more are becoming available every day. Such documents represent a massive amount of information that is easily accessible. Seeking value in this huge ... -
Intelligence by Design: Principles of Modularity and Coordination for Engineerin
(2001-09-01)All intelligence relies on search --- for example, the search for an intelligent agent's next action. Search is only likely to succeed in resource-bounded agents if they have already been biased towards finding the right ...
