On Sparse Graph Fourier Transform
Seyed Hamid Safavi, Manas Khatua, Ngai-Man Cheung +1
In this paper, we propose a new regression-based algorithm to compute Graph Fourier Transform (GFT). Our algorithm allows different regularizations to be included when computing th…
A Compressive Method for Centralized PSD Map Construction with Imperfect Reporting Channel
Mohammad Eslami, Seyed Hamid Safavi, Farah Torkamani-Azar +1
Spectrum resources management of growing demands is a challenging problem and Cognitive Radio (CR) known to be capable of improving the spectrum utilization. Recently, Power Spectr…
Perceptual Compressive Sensing based on Contrast Sensitivity Function: Can we avoid non-visible redundancies acquisition?
Seyed Hamid Safavi, Farah Torkamani-Azar
In this paper, we propose a novel CS approach in which the acquisition of non-visible information is also avoided.
A novel Adaptive weighted Kronecker Compressive Sensing
Seyed Hamid Safavi, Farah Torkamani-Azar
Recently, multidimensional signal reconstruction using a low number of measurements is of great interest. Therefore, an effective sampling scheme which should acquire the most info…
Simultaneous Low-rank Component and Graph Estimation for High-dimensional Graph Signals: Application to Brain Imaging
Rui Liu, Hossein Nejati, Seyed Hamid Safavi +1
We propose an algorithm to uncover the intrinsic low-rank component of a high-dimensional, graph-smooth and grossly-corrupted dataset, under the situations that the underlying grap…
