The slug flow pattern is one of the most common gas-liquid patterns in multiphase transportation pipelines, particularly oil and gas industry. This can cause severe problems for industrial processes. Hence, a detailed description spatial distribution different phases pipe needed automated process control calibration predictive models. In this paper, deep-learning based image processing techniqu...

ONR has been funding Prof. Roy and Prof. Baldwin to perform research on Event Representation in Humans and Machines. Prof. Roy's portion of that research involves developing an unsupervised learning system that acquires structured event representations of human activity grounded in naturalistic video observations. The output of that system is to be an action lexicon that encodes recurrent hiera...

This paper examines audio-visual speaker veri cation using a novel adaptation of fused hidden Markov models, in comparison to output fusion of individual classi ers in the audio and video modalities. A comparison of both hidden Markov model (HMM) and Gaussian mixture model (GMM) classi ers in both modalities under output fusion shows that the choice of audio classi er is more important than vid...
