H.264 Format/Bitrate/Quality Tradeoff Study
Maximizing transmitted video quality at the highest resolution and highest frame rate is desirable,but multiple approaches can be employed to maximize transmission quality for the video at a given bitrate.

Long Range Audio and Audio-Visual Event Detection Using a Laser Doppler Vibrometer
In this work, in addition to a geo-calibrated electro-optical camera, we propose to use a novel optical sensor for real-time audio sensing, which allows us to capture acoustic signals from…

Automatic Blood Vessel Localization in Small Field of View Eye Images
We present an automatic technique for localizing vessels in small field of view images using multi-scale matched filters. We also estimate local vessel properties - width and orientation - along…

Active Botnet Probing to Identify Obscure Command and Control Channels
We consider the problem of identifying obscure chat-like botnet command and control (C & C) communications, which are indistinguishable from human-human communication using traditional signature-based techniques.

Gaussian Process Learning for Cyber-Attack Early Warning
We present a framework to estimate the relevance of each network with respect to each network. In particular, we model each attacker's relevance as a function over the networks.
