Artifact reduction for separable non-local means
Sanjay Ghosh, Kunal N. Chaudhury
It was recently demonstrated [J. Electron. Imaging, 25(2), 2016] that one can perform fast non-local means (NLM) denoising of one-dimensional signals using a method called lifting.…
On a registration-based approach to sensor network localization
Rajat Sanyal, Monika Jaiswal, Kunal Narayan Chaudhury
We consider a registration-based approach for localizing sensor networks from range measurements. This is based on the assumption that one can find overlapping cliques spanning the…
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…
