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 ... -
Distributed resource allocation and performance optimization for video communication over mesh networks based on swarm intelligence
(University of Missouri--Columbia, 2007)Mesh networking technologies allow a system of communication devices to communicate with each other over a dynamic and self-organizing wired or wireless network from everywhere at anytime. Large-scale mesh communication ... -
Efficient H.264 video coding with a working memory of objects
(University of Missouri--Columbia, 2009)Efficient spatiotemporal prediction to remove the source redundancy is critical in video coding. The newest international standard H.264 video coding introduces several advanced features, such as multiple-frame motion ... -
Embedded system design and power-rate-distortion optimization for video encoding under energy constraints
(University of Missouri--Columbia, 2007)The portable devices used in video communication application are powered by batteries. Video encoding schemes, however, are often computationally intensive and energy-demanding, even after being fully optimized with existing ... -
Ensemble video object cut in highly dynamic scenes
(University of Missouri--Columbia, 2014)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] We consider video object cut as an ensemble of framelevel background-foreground object classifiers which fuses information across frames and refine ... -
Fast and reliable hand action recognition

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 ... -
Image search with LSH and shape context
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Partial-duplicate image search is a problem of searching the query image cropped from the same original image from a large database. Kd-tree have a ... -
Indoor human activites recognition using audio signals based on support vector machines and convolutional neural networks
(University of Missouri--Columbia, 2018)Indoor human activities recognition can be of great importance in our daily life, especially for surveillance and security purposes, such as informing elderly people affected in hearing capabilities about environmental ... -
Moving objects detection and labeling in surveillance videos
(University of Missouri--Columbia, 2014)Moving objects detection and labeling are an important component of intelligent surveillance systems. Accurate classification of moving objects allows the monitoring system to react to certain events of interest. In this ... -
Object detection and classification using shape feature
(University of Missouri--Columbia, 2014)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] We develop a set of methods to represent and detect shapes in images. We first develop new shape descriptors that are robust to deformation while being ... -
Optimal video sensing strategy and performance analysis for wireless video sensors under delay constraints
(University of Missouri--Columbia, 2005)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] A wireless sensor network (WSN) is a system of spatially distributed sensors that capture, process and transmit information over a mobile wireless ... -
