Compressive Sensing of ECG Signals using Plug-and-Play Regularization
Unni VS, Ruturaj Gavaskar, Kunal Narayan Chaudhury
Compressive Sensing (CS) has recently attracted attention for ECG data compression. In CS, an ECG signal is projected onto a small set of random vectors. Recovering the original si…
On Plug-and-Play Regularization using Linear Denoisers
Ruturaj G. Gavaskar, Chirayu D. Athalye, Kunal N. Chaudhury
In plug-and-play (PnP) regularization, the knowledge of the forward model is combined with a powerful denoiser to obtain state-of-the-art image reconstructions. This is typically d…
Fixed-Point and Objective Convergence of Plug-and-Play Algorithms
Pravin Nair, Ruturaj G. Gavaskar, Kunal N. Chaudhury
A standard model for image reconstruction involves the minimization of a data-fidelity term along with a regularizer, where the optimization is performed using proximal algorithms…
Plug-and-play ISTA converges with kernel denoisers
Ruturaj G. Gavaskar, Kunal N. Chaudhury
Plug-and-play (PnP) method is a recent paradigm for image regularization, where the proximal operator (associated with some given regularizer) in an iterative algorithm is replaced…
On the Proof of Fixed-Point Convergence for Plug-and-Play ADMM
Ruturaj G. Gavaskar, Kunal N. Chaudhury
In most state-of-the-art image restoration methods, the sum of a data-fidelity and a regularization term is optimized using an iterative algorithm such as ADMM (alternating directi…
Fast Adaptive Bilateral Filtering
Ruturaj G. Gavaskar, Kunal N. Chaudhury
In the classical bilateral filter, a fixed Gaussian range kernel is used along with a spatial kernel for edge-preserving smoothing. We consider a generalization of this filter, the…
