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…
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…
Optimized Fourier Bilateral Filtering
Sanjay Ghosh, Pravin Nair, Kunal N. Chaudhury
We consider the problem of approximating a truncated Gaussian kernel using Fourier (trigonometric) functions. The computation-intensive bilateral filter can be expressed using fast…
