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…
Guided Nonlocal Patch Regularization and Efficient Filtering-Based Inversion for Multiband Fusion
Unni V. S., Pravin Nair, Kunal N. Chaudhury
In multiband fusion, an image with a high spatial and low spectral resolution is combined with an image with a low spatial but high spectral resolution to produce a single multiban…
Plug-and-Play Regularization using Linear Solvers
Pravin Nair, Kunal N. Chaudhury
There has been tremendous research on the design of image regularizers over the years, from simple Tikhonov and Laplacian to sophisticated sparsity and CNN-based regularizers. Coup…
On Exact and Robust Recovery for Plug-and-Play Compressed Sensing
Ruturaj G. Gavaskar, Chirayu D. Athalye, Kunal N. Chaudhury
In Plug-and-Play (PnP) algorithms, an off-the-shelf denoiser is used for image regularization. PnP yields state-of-the-art results, but its theoretical aspects are not well underst…
Averaged Deep Denoisers for Image Regularization
Pravin Nair, Kunal N. Chaudhury
Plug-and-Play (PnP) and Regularization-by-Denoising (RED) are recent paradigms for image reconstruction that leverage the power of modern denoisers for image regularization. In par…
