A PARAFAC-based technique for detection and localization of multiple targets in a MIMO radar system
In this paper, we show that the problem of detection and localization of multiple targets in a bistatic MIMO radar system can be solved by Parallel Factor (PARAFAC) analysis. Our ...

A reduced-reference video structural similarity metric based on no-reference estimation of channel-induced distortion
The reduced-reference (RR) approximation of a full-reference (FR) video quality assessment method is a convenient way to build evaluation metrics which are both intrinsically well...

On the recovery of nonnegative sparse vectors from sparse measurements inspired by expanders
This paper studies compressed sensing for the recovery of non-negative sparse vectors from a smaller number of measurements than the ambient dimension of the unknown vector. We fo...
