Modeling, Estimation, and Control of Robot-Soil Interactions
(2001-09-01)
This thesis presents the development of hardware, theory, and experimental methods to enable a robotic manipulator arm to interact with soils and estimate soil properties from interaction forces. Unlike the majority of ...
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 ...
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 ...
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 ...
Role of Low-level Mechanisms in Brightness Perception
(2001-08-01)
Brightness judgments are a key part of the primate brain's visual analysis of the environment. There is general consensus that the perceived brightness of an image region is based not only on its actual luminance, but also ...
Multiclass Classification of SRBCTs
(2001-08-25)
A novel approach to multiclass tumor classification using Artificial Neural Networks (ANNs) was introduced in a recent paper cite{Khan2001}. The method successfully classified and diagnosed small, round blue cell tumors ...
Biologically Plausible Neural Circuits for Realization of Maximum Operations
(2001-09-01)
Object recognition in the visual cortex is based on a hierarchical architecture, in which specialized brain regions along the ventral pathway extract object features of increasing levels of complexity, accompanied by greater ...
Perceptually-based Comparison of Image Similarity Metrics
(2001-07-01)
The image comparison operation ??sessing how well one image matches another ??rms a critical component of many image analysis systems and models of human visual processing. Two norms used commonly for this purpose are L1 ...
Contextual Priming for Object Detection
(2001-09-01)
There is general consensus that context can be a rich source of information about an object's identity, location and scale. In fact, the structure of many real-world scenes is governed by strong configurational rules akin ...
Experimental Markets for Product Concepts
(2001-07-01)
Market prices are well known to efficiently collect and aggregate diverse information regarding the value of commodities and assets. The role of markets has been particularly suitable to pricing financial securities. This ...
