A system for change detection and human recognition in voxel space using stereo vision
(University of Missouri--Columbia, 2010)
Image space change detection algorithms do not adequately address the complexities in real-world dynamic environments. With few exceptions, these algorithms rely on pixel-level information to detect proper foreground change. ...
Human fall detection using a circular audio sensor array
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] According to the U.S. Census Bureau estimate (March 2010), there were 38.9 million people 65 years and older in the United States in 2008. In 2005, 15,800 people 65 years...
Automated video processing and scene understanding for intelligent video surveillance
(University of Missouri--Columbia, 2010)
Recent advances in key technologies have enabled the deployment of surveillance video cameras on various platforms. There is an urgent need to develop advanced computational methods and tools for automated video processing ...
Hefner model parameters for power IGBTS under pulsed power conditions
(University of Missouri--Columbia, 2010)
While the power insulated gate bipolar transistor (IGBT) is used in many applications, it is not well characterized under pulsed power conditions. This makes the IGBT difficult to model for solid state pulsed power ...
Significance-linked connected component analysis+ for wavelet image coding
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The Significance-Linked Connected Component Analysis+ (SLCCA+) is a efficient wavelet image coding algorithm that extends SLCCA by using new data ...
Gas pumping efect from dielectrophoretically driven liquid droplet in a closed microfluidic channel
(University of Missouri--Columbia, 2010)
This dissertation describes the study of dielectrophotoretically controllable droplet's movement in a closed-side microfluidic channel for a micro gas pump application. A micro gas pump using a aqueous core has been ...
Floor sensor development using signal scavenging for personnel detection system
(University of Missouri--Columbia, 2010)
Falls have been a major cause of injuries likes fractures, head trauma in elder people. In many cases, these injuries have been fatal. This being a major concern of the Alzheimer's Association, a 'Smart Carpet' to detect ...
Investigation of polarimetric coherence optimization in persistent scatterer interferometry
(University of Missouri--Columbia, 2010)
Interferometric Synthetic Aperture Radar (InSAR) provides a means of imaging small deformations of the Earth's surface (millimeter scale). Furthermore, interferometric point target analysis (IPTA) and time-series analyses ...
On the use of multiple emitters to improve the TDOA source localization accuracy in the presence of random sensor position errors
(University of Missouri--Columbia, 2010)
It is known that random sensor position errors can significantly degrade the TDOA source localization accuracy. In this thesis, we conduct a systematic study on using the calibration emitters to mitigate the effect of ...
Target geolocation from airborne video without terrain data
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The task of geolocating targets from airborne video is required for many applications in surveillance, law enforcement, reconnaissance, etc. The usual ...
Frame interpolation in H.264
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In video transmission over low-bandwidth networks, videos are often encoded at low frame rates. At the decoder side, frame interpolation is often ...
Optically enhanced nano-forest cathodes
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Optically enhanced nano-forest cathodes are electron sources developed for high power devices. The principle of cathode operation is based on coherent ...
Enhancing the IKE preshared key authentication method
(University of Missouri--Columbia, 2006)
Internet Key Exchange (IKE) protocol is part of the IP Security (IPsec) protocol suite. It is responsible for generating and maintaining Security Associates and for establishing session keys between two entities before ...
Influence of gamma irradiation on chemical vapor deposited boron-doped diamond films

Atmospheric effects on near-infrared free space optical communication links
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] High-bandwidth optical communication systems are increasingly in demand. As radio frequency (RF) telecommunications approach its natural limit in ...
Design of a signal scavenging sensor system for passive monitoring in elder care technology
(University of Missouri--Columbia, 2010)
This thesis describes sensors designed for a non-obtrusive monitoring system to detect and track the elderly adults walking on the carpet. The sensors are thin metal foils which detect environmental or scavenged energy. ...
Data control for signal scavenging for a personnel detection system
(University of Missouri--Columbia, 2010)
Injurious falls have been one of the major problems in elderly people and not providing medical assistance to those patients on time may increase complications. We developed a "Smart Carpet", which detects the personal ...
