Linearized ADMM and Fast Nonlocal Denoising for Efficient Plug-and-Play Restoration
Unni V. S., Sanjay Ghosh, Kunal N. Chaudhury
In plug-and-play image restoration, the regularization is performed using powerful denoisers such as nonlocal means (NLM) or BM3D. This is done within the framework of alternating…
Pruned non-local means
Sanjay Ghosh, Amit K. Mandal, Kunal N. Chaudhury
In Non-Local Means (NLM), each pixel is denoised by performing a weighted averaging of its neighboring pixels, where the weights are computed using image patches. We demonstrate th…
Fast and High-Quality Bilateral Filtering Using Gauss-Chebyshev Approximation
Sanjay Ghosh, Kunal N. Chaudhury
The bilateral filter is an edge-preserving smoother that has diverse applications in image processing, computer vision, computer graphics, and computational photography. The filter…
Fast Bilateral Filtering of Vector-Valued Images
Sanjay Ghosh, Kunal N. Chaudhury
In this paper, we consider a natural extension of the edge-preserving bilateral filter for vector-valued images. The direct computation of this non-linear filter is slow in practic…
On Fast Bilateral Filtering using Fourier Kernels
Sanjay Ghosh, Kunal N. Chaudhury
It was demonstrated in earlier work that, by approximating its range kernel using shiftable functions, the non-linear bilateral filter can be computed using a series of fast convol…
