A compact representation for 3D animation using octrees and affine transformation
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] We present a new and compact 3D representation for non-rigid objects using motion vectors between two consecutive frames. Our method relies on an ...
Algorithm design and error analysis of quantized RSSI based localization in wireless sensor networks
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Wireless Sensor Network localization is an important aspect in sensor network applications such as tracking and monitoring. The general goal of ...
Knowledge-driven multidimensional indexing for content-based information retrieval
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Media data are being generated at rates unimaginable only years ago. We face challenges in providing efficient and accurate access to media content, ...
MUPrimer : a tool for finding allele specific PCR-primers for homologous gene sequences
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Polymerase chain reaction (PCR) amplification of specific regions of DNA has proven to be a powerful tool in molecular biology research. Synthetic ...
Experimental study of localization in sensor networks and design of adaptive localization algorithms
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] We design an experimental framework to evaluate localization methods for sensor networks. We use this framework to evaluate three existing localization ...
Sketch-based navigation for mobile robots using qualitative landmark states
(University of Missouri--Columbia, 2007)
In this work, a system for navigating a mobile robot along a sketched route is proposed. The sketch is drawn on a PDA screen by a human operator and contains approximate landmarks and a path, similar to a sketch provided ...
Enhancement of adaptive de-correlation filtering separation model for robust speech recognition
(University of Missouri--Columbia, 2007)
The development of automatic speech recognition (ASR) technology has enabled an increasing number of applications. However, the robustness of ASR under real acoustic environments still remains to be a challenge for practical applications...
Ensemble methods in large vocabulary continuous speech recognition
(University of Missouri--Columbia, 2008)
Combining a group of classifiers and therefore improving the overall classification performance is a young and promising direction in Large Vocabulary Continuous Speech Recognition (LVCSR). Previous works on acoustic ...
Domain-concept mining : an efficient on-demand data mining approach
(University of Missouri--Columbia, 2008)
Traditional brute-force association mining approaches, when applied to large datasets, are thorough but inefficient due to computational complexity. A low global minimum probability threshold can worsen this complexity by ...
A system for access and administration of fault-tolerant web services
(University of Missouri--Columbia, 2005)
Web Services, a recent development in web technology, enables programs (services) on the World Wide Web (WWW) to communicate with each other. A program (web service) available on the WWW has to be robust to serve the vast number of users on the WWW...
Improvement of decoding engine & phonetic decision tree in acoustic modeling for online large vocabulary conversational speech recognition
(University of Missouri--Columbia, 2007)
In this work, new approaches are proposed for online large vocabulary conversational speech recognition, including a fast confusion network algorithm, novel features and a Random Forests based classifier for word confidence ...
Real-time visualization of massive imagery and volumetric datasets
(University of Missouri--Columbia, 2006)
The visualization of extremely large multi-dimensional datasets requires highly scalable geometric algorithms. We consider an algorithm to be scalable if its complexity remains constant independent of the size of the ...
Real-time speaker-independent large vocabulary continuous speech recoginition
(University of Missouri--Columbia, 2005)
In this dissertation, a real-time decoding engine for speaker-independent large vocabulary continuous speech recognition (LVCSR) is presented. Three indispensable and correlated performance measurements -- accuracy, speed, ...
