Multiview Sensing With Unknown Permutations: An Optimal Transport Approach

no code implementations12 Mar 2021 Yanting Ma, Petros T. Boufounos, Hassan Mansour, Shuchin Aeron

In several applications, including imaging of deformable objects while in motion, simultaneous localization and mapping, and unlabeled sensing, we encounter the problem of recovering a signal that is measured subject to unknown permutations.

Two-Dimensional Non-Line-of-Sight Scene Estimation from a Single Edge Occluder

no code implementations16 Jun 2020 Sheila W. Seidel, John Murray-Bruce, Yanting Ma, Christopher Yu, William T. Freeman, Vivek K Goyal

Previous work has leveraged the vertical nature of the edge to demonstrate 1D (in angle measured around the corner) reconstructions of moving and stationary hidden scenery from as little as a single photograph of the penumbra.

On the modes of convergence of Stochastic Optimistic Mirror Descent (OMD) for saddle point problems

no code implementations2 Aug 2019 Yanting Ma, Shuchin Aeron, Hassan Mansour

In this article, we study the convergence of Mirror Descent (MD) and Optimistic Mirror Descent (OMD) for saddle point problems satisfying the notion of coherence as proposed in Mertikopoulos et al. We prove convergence of OMD with exact gradients for coherent saddle point problems, and show that monotone convergence only occurs after some sufficiently large number of iterations.

Accelerated Image Reconstruction for Nonlinear Diffractive Imaging

no code implementations4 Aug 2017 Yanting Ma, Hassan Mansour, Dehong Liu, Petros T. Boufounos, Ulugbek S. Kamilov

The problem of reconstructing an object from the measurements of the light it scatters is common in numerous imaging applications.
