Geometric Invariants for Sparse Unknown View Tomography
Mona Zehni, Shuai Huang, Ivan Dokmanić +1
In this paper, we study a 2D tomography problem for point source models with random unknown view angles. Rather than recovering the projection angles, we reconstruct the model thro…

A Spectral Method for Stable Bispectrum Inversion with Application to Multireference Alignment
Hua Chen, Mona Zehni, Zhizhen Zhao
We focus on an alignment-free method to estimate the underlying signal from a large number of noisy randomly shifted observations. Specifically, we estimate the mean, power spectru…

Multi-Segment Reconstruction Using Invariant Features
Mona Zehni, Minh N. Do, Zhizhen Zhao
Multi-segment reconstruction (MSR) problem consists of recovering a signal from noisy segments with unknown positions of the observation windows. One example arises in DNA sequence…
