Robust Kronecker Product PCA for Spatio-Temporal Covariance Estimation
Kristjan Greenewald, Alfred Hero
Kronecker PCA involves the use of a space vs. time Kronecker product decomposition to estimate spatio-temporal covariances. In this work the addition of a sparse correction factor…
Kronecker PCA Based Spatio-Temporal Modeling of Video for Dismount Classification
Kristjan H. Greenewald, Alfred O. Hero
We consider the application of KronPCA spatio-temporal modeling techniques [Greenewald et al 2013, Tsiligkaridis et al 2013] to the extraction of spatiotemporal features for video…
Regularized Block Toeplitz Covariance Matrix Estimation via Kronecker Product Expansions
Kristjan Greenewald, Alfred O. Hero
In this work we consider the estimation of spatio-temporal covariance matrices in the low sample non-Gaussian regime. We impose covariance structure in the form of a sum of Kroneck…
Detection of Anomalous Crowd Behavior Using Spatio-Temporal Multiresolution Model and Kronecker Sum Decompositions
Kristjan Greenewald, Alfred Hero
In this work we consider the problem of detecting anomalous spatio-temporal behavior in videos. Our approach is to learn the normative multiframe pixel joint distribution and detec…
