Large-Scale Sensor Network Localization via Rigid Subnetwork Registration
Kunal N. Chaudhury, Yuehaw Khoo, Amit Singer
In this paper, we describe an algorithm for sensor network localization (SNL) that proceeds by dividing the whole network into smaller subnetworks, then localizes them in parallel…
Global registration of multiple point clouds using semidefinite programming
Kunal N. Chaudhury, Yuehaw Khoo, Amit Singer
Consider points in and local coordinate systems that are related through unknown rigid transforms. For each point we are given (possibly noisy) measurements…
On the convergence of the IRLS algorithm in Non-Local Patch Regression
Kunal N. Chaudhury
Recently, it was demonstrated in [CS2012,CS2013] that the robustness of the classical Non-Local Means (NLM) algorithm [BCM2005] can be improved by incorporating $\ell^p (0 < p \leq…
Decay properties of Riesz transforms and steerable wavelets
John Paul Ward, Kunal Narayan Chaudhury, Michael Unser
The Riesz transform is a natural multi-dimensional extension of the Hilbert transform, and it has been the object of study for many years due to its nice mathematical properties. M…
