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…
Convergence Analysis of Nonconvex ADMM for Rigid Registration
Aditya V. Singh, Kunal N. Chaudhury
We consider the problem of rigid registration, where we wish to jointly register multiple point sets via rigid transforms. This arises in applications such as sensor network locali…
On Uniquely Registrable Networks
Aditya V. Singh, Kunal N. Chaudhury
Consider a network with nodes in -dimensional Euclidean space, and subsets of these nodes . Assume that the nodes in a given are observed in a loca…
Least-squares registration of point sets over SE (d) using closed-form projections
Sk. Miraj Ahmed, Niladri Ranjan Das, Kunal Narayan Chaudhury
Consider the problem of registering multiple point sets in some -dimensional space using rotations and translations. Assume that there are sets with common points, and moreover…
Fast High-Dimensional Kernel Filtering
Pravin Nair, Kunal N. Chaudhury
The bilateral and nonlocal means filters are instances of kernel-based filters that are popularly used in image processing. It was recently shown that fast and accurate bilateral f…
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…
