On the stability of scale-space metrics
William Leeb
We study the stability of a classical family of metrics defined over functions' Gaussian scale-space representations, focusing on the comparison of images (functions of two variabl…
On sliced Cramér metrics
William Leeb
This paper studies the family of sliced Cramér metrics, quantifying their stability under distortions of the input functions. Our results bound the growth of the sliced Cramér dist…
Matrix Denoising with Partial Noise Statistics: Optimal Singular Value Shrinkage of Spiked F-Matrices
Matan Gavish, William Leeb, Elad Romanov
We study the problem of estimating a large, low-rank matrix corrupted by additive noise of unknown covariance, assuming one has access to additional side information in the form of…
Dihedral multi-reference alignment
Tamir Bendory, Dan Edidin, William Leeb +1
We study the dihedral multi-reference alignment problem of estimating the orbit of a signal from multiple noisy observations of the signal, acted on by random elements of the dihed…
On metrics robust to noise and deformations
William Leeb
We study the properties of a family of distances between functions of a single variable. These distances are examples of integral probability metrics, and have been used previously…
Super-resolution multi-reference alignment
Tamir Bendory, Ariel Jaffe, William Leeb +2
We study super-resolution multi-reference alignment, the problem of estimating a signal from many circularly shifted, down-sampled, and noisy observations. We focus on the low SNR…
