Score-based diffusion priors for multi-target detection
Alon Zabatani, Shay Kreymer, Tamir Bendory
Multi-target detection (MTD) is the problem of estimating an image from a large, noisy measurement that contains randomly translated and rotated copies of the image. Motivated by t…
Phase retrieval with semi-algebraic and ReLU neural network priors
Tamir Bendory, Nadav Dym, Dan Edidin +1
The key ingredient to retrieving a signal from its Fourier magnitudes, namely, to solve the phase retrieval problem, is an effective prior on the sought signal. In this paper, we s…
Synchronization by Eigenvectors of Dual Quaternion Matrices
Ido Hadi, Tamir Bendory, Nir Sharon
In synchronization problems, the goal is to estimate elements of a group from noisy measurements of their ratios. A popular estimation method for synchronization is the spectral me…
Detection and Recovery of Hidden Submatrices
Marom Dadon, Wasim Huleihel, Tamir Bendory
In this paper, we study the problems of detection and recovery of hidden submatrices with elevated means inside a large Gaussian random matrix. We consider two different structures…
Expectation-maximization for structure determination directly from cryo-EM micrographs
Shay Kreymer, Amit Singer, Tamir Bendory
A single-particle cryo-electron microscopy (cryo-EM) measurement, called a micrograph, consists of multiple two-dimensional tomographic projections of a three-dimensional (3-D) mol…
Finite alphabet phase retrieval
Tamir Bendory, Dan Edidin, Ivan Gonzalez
We consider the finite alphabet phase retrieval problem: recovering a signal whose entries lie in a small alphabet of possible values from its Fourier magnitudes. This problem aris…
