A model-based, generative and stochastic method for human motion capture using hierarchical particle filters
(University of Missouri--Columbia, 2011)
hierarchical framework for tracking human pose. Extensive experiments on a public benchmark dataset demonstrate comparable tracking errors to the state-of-the-art and up to 60% computational reduction....
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)
locations as a special case. Moreover, scenario (iv) can be viewed as the extension of scenario (iii) in the sense that the unknown source positions are now generated by a moving source. For each localization scenario, we investigate the amount...
Significance-linked connected component analysis+ for wavelet image coding
(University of Missouri--Columbia, 2010)
(DOR) and SLCCA+ use a definition of context model for the adaptive arithmetic coding. Extensive computer experiments on both natural and texture images show convincingly that the proposed SLCCA+ outperforms SLCCA. For example, for the Lena image, at 0...
Nanogap embedded silver gratings for surface plasmon enhanced fluorescence
(University of Missouri--Columbia, 2012)
Plasmonic nanostructures have been extensively used in the past few decades for applications in sub-wavelength optics, data storage, optoelectronic circuits, microscopy and bio-photonics. The enhanced electric field produced within a few hundred...
Experimental evaluation of characteristic temperature with varying duty cycles in 2μm vertical cavity surface emitting lasers due to external optical pumping

and perspective changes. Collaborative video compression for UAV surveillance network. Based on distributed video coding, we develop a collaborative video compression scheme for a UAV surveillance network. Our extensive experimental results demonstrate...
Characterizing carrier transport in silicon thin film metal semiconductor metal structures
(University of Missouri--Columbia, 2011)
in studies related to the development of optoelectronic devices. In this study, extensive three dimensional simulations and analysis of thin-film silicon structures have been carried out to observe and interpret the physics of charge transport in scaled down...
Design and application of conformal patch antenna for near-field imaging and object detection
(University of Missouri--Columbia, 2013)
extensive data collection and processing computations. This technique is based on the analysis of the transmission and reflection signal from the targeted object. The antenna used in the scanning involves three operational modes, which include: planar scan...
The ferroelectric plasma thruster
(University of Missouri--Columbia, 2008)
Micropropulsion is an enabling technology for microspacecraft. As requirements for microspacecraft missions become more demanding, so do the requirements for micropropulsion. Therefore, existing technologies require ...
Object detection for big dataObject detection for big data

We have observed significant advances in object detection over the past few decades and gladly seen the related research has began to contribute to the world: Vehicles could automatically stop before hitting any pedestrian; ...
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 ...
