Near-optimal bounds for signal recovery from blind phaseless periodic short-time Fourier transform
Tamir Bendory, Chi-yu Cheng, Dan Edidin
We study the problem of recovering a signal from samples of its phaseless periodic short-time Fourier transform (STFT): the magnitude of the Fourier transform of…
An approximate expectation-maximization for two-dimensional multi-target detection
Shay Kreymer, Amit Singer, Tamir Bendory
We consider the two-dimensional multi-target detection (MTD) problem of estimating a target image from a noisy measurement that contains multiple copies of the image, each randomly…
Generalized autocorrelation analysis for multi-target detection
Ye'Ela Shalit, Ran Weber, Asaf Abas +2
We study the multi-target detection problem of recovering a target signal from a noisy measurement that contains multiple copies of the signal at unknown locations. Motivated by th…
Sparse multi-reference alignment: sample complexity and computational hardness
Tamir Bendory, Oscar Mickelin, Amit Singer
Motivated by the problem of determining the atomic structure of macromolecules using single-particle cryo-electron microscopy (cryo-EM), we study the sample and computational compl…
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…
Compactification of the Rigid Motions Group in Image Processing
Tamir Bendory, Ido Hadi, Nir Sharon
Image processing problems in general, and in particular in the field of single-particle cryo-electron microscopy, often require considering images up to their rotations and transla…
An accelerated expectation-maximization algorithm for multi-reference alignment
Noam Janco, Tamir Bendory
The multi-reference alignment (MRA) problem entails estimating an image from multiple noisy and rotated copies of itself. If the noise level is low, one can reconstruct the image b…
Two-dimensional multi-target detection: an autocorrelation analysis approach
Shay Kreymer, Tamir Bendory
We consider the two-dimensional multi-target detection problem of recovering a target image from a noisy measurement that contains multiple copies of the image, each randomly rotat…
The generalized method of moments for multi-reference alignment
Asaf Abas, Tamir Bendory, Nir Sharon
This paper studies the application of the generalized method of moments (GMM) to multi-reference alignment (MRA): the problem of estimating a signal from its circularly-translated…
Signal recovery from a few linear measurements of its high-order spectra
Tamir Bendory, Dan Edidin, Shay Kreymer
The -th order spectrum is a polynomial of degree in the entries of a signal , which is invariant under circular shifts of the signal. For , this p…
Multi-target detection with rotations
Tamir Bendory, Ti-Yen Lan, Nicholas F. Marshall +2
We consider the multi-target detection problem of estimating a two-dimensional target image from a large noisy measurement image that contains many randomly rotated and translated…
