Geometric scale-space framework for the analysis of hyperspectral imagery
(2007)
This work introduces a framework for a fast and algorithmically scalable multiscale representation and segmentation of hyperspectral imagery. The framework is based on the scale-space representation generated by geometric ...
An adaptive spectrally weighted structure tensor applied to tensor anisotropic nonlinear diffusion for hyperspectral images
(2012)
The structure tensor for vector valued images is most often defined as the average of the scalar structure tensors in each band. The problem with this definition is the assumption that all bands provide the same amount ...
Unsupervised unmixing of hyperspectral imagery using the constrained positive matrix factorization
(2007)
In hyperspectral imaging, hundreds of images are taken at narrow and contiguous spectral bands providing us with high spectral resolution spectral signatures that can be used to discriminate between objects. In many ...
M-loc: real time location system for wireless mesh networks
(2008)
This thesis presents the design and implementation of a real time location system (RTLS) for wireless mesh networks. The system uses the received signal strength as the method of distance measurement. A prototype of this ...
Seaweb: a web portal for the censsis seabed testbed
(2006)
SeaBED is a facility developed at the NSF Center for Subsurface Sensing and Imaging Systems (CenSSIS) to study applications of hyperspectral imaging to aquatic subsurface sensing. This report describes SeaWEB, a web based ...
A reconfiguration algorithm for a dc zonal electric distribution system based on graph-theory methods
(2009)
In many applications, self contained Electric Power Distribution Systems (EPDS) require high survivability under fault conditions. A fault produces an immediate change in the system topology resulting in potential loss of ...
A vector sift operator for interest point detection in vector imagery and its application to multispectral and hyperspectral imagery
(2009)
This research work presents an algorithm for automated detection of interest points in vector images such as RGB and hyperspectral. Interest points are features of the image that capture information from its neighbors are ...
A study of equation-free methods for simulation of power electronics systems
(2010)
Power electronics is a field that has a high demand today and it also has a great importance in our technology world. Therefore, it is necessary to develop modeling and simulation tools that allow the development of system ...
Diseño de un esquema de control para extracción de máxima potencia en un sistema turbina-generador eólico de baja potencia
(2010)
This document presents the modeling of a wind turbine-generator system and developing a control scheme for maximum power extraction. The system comprises a low-power variable speed wind rotor coupled to a squirrel cage ...
Evaluation of different structured models for target detection in hyperspectral imagery
(2010)
Target detection is an essential component in defense, security and medical applications of hyperspectral imagery. Structured and unstructured models are used to model variability of spectral signatures for the design of ...
