Proceedings ArticleDOI
Region-Based Statistical Background Modeling for Foreground Object Segmentation
TL;DR: A novel region-based scheme for dynamically modeling time-evolving statistics of video background, leading to an effective segmentation of foreground moving objects for a video surveillance system through introducing dynamic background region merging and splitting.
Proceedings ArticleDOI
A new method to compute optimal periodic sampling patterns
TL;DR: An algorithm based on sparse reconstruction techniques, which is able to find the sparsest sampling pattern that permits perfect reconstruction of the sampled signal is proposed, which results in a sparse subset of samples that results in an ideal condition number for its equivalent sub-DFT matrix.
Proceedings ArticleDOI
Eigenbeam transmission over line-of-sight MIMO channels for fixed microwave links
TL;DR: It is demonstrated that the Tx eigenbeams can be defined without channel state information at the transmitter and that the beams admit an insightful physical interpretation.
Journal ArticleDOI
Estimation of damped and undamped sinusoids with application to analysis of electromagnetic FDTD simulation data
TL;DR: In this paper, a frequency-domain subspace method was proposed to obtain accurate frequency and damping estimates in a selected frequency band, which can reduce the simulation time by several orders of magnitude.
