Non-Local Patch Regression: Robust Image Denoising in Patch Space
Kunal N. Chaudhury, Amit Singer
It was recently demonstrated in [Chaudhury et al.,Non-Local Euclidean Medians,2012] that the denoising performance of Non-Local Means (NLM) can be improved at large noise levels by…

Fourier-Bessel rotational invariant eigenimages
Zhizhen Zhao, Amit Singer
We present an efficient and accurate algorithm for principal component analysis (PCA) of a large set of two dimensional images, and, for each image, the set of its uniform rotation…

Non-Local Euclidean Medians
Kunal N. Chaudhury, Amit Singer
In this letter, we note that the denoising performance of Non-Local Means (NLM) at large noise levels can be improved by replacing the mean by the Euclidean median. We call this ne…
