Image detection using combinatorial auction
Simon Anuk, Tamir Bendory, Amichai Painsky
This paper studies the optimal solution of the classical problem of detecting the location of multiple image occurrences in a two-dimensional, noisy measurement. Assuming the image…
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…
Signal enhancement for two-dimensional cryo-EM data processing
Guy Sharon, Yoel Shkolnisky, Tamir Bendory
Different tasks in the computational pipeline of single-particle cryo-electron microscopy (cryo-EM) require enhancing the quality of the highly noisy raw images. To this end, we de…
Unsupervised particle sorting for cryo-EM using probabilistic PCA
Gili Weiss-Dicker, Amitay Eldar, Yoel Shkolinsky +1
Single-particle cryo-electron microscopy (cryo-EM) is a leading technology to resolve the structure of molecules. Early in the process, the user detects potential particle images i…
Denoiser-based projections for 2-D super-resolution multi-reference alignment
Jonathan Shani, Tom Tirer, Raja Giryes +1
We study the 2-D super-resolution multi-reference alignment (SR-MRA) problem: estimating an image from its down-sampled, circularly-translated, and noisy copies. The SR-MRA problem…
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…
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…
Image recovery from rotational and translational invariants
Nicholas F. Marshall, Ti-Yen Lan, Tamir Bendory +1
We introduce a framework for recovering an image from its rotationally and translationally invariant features based on autocorrelation analysis. This work is an instance of the mul…
Heterogeneous multireference alignment for images with application to 2-D classification in single particle reconstruction
Chao Ma, Tamir Bendory, Nicolas Boumal +2
Motivated by the task of 2-D classification in single particle reconstruction by cryo-electron microscopy (cryo-EM), we consider the problem of heterogeneous multireference alignme…
