Near-Optimal Coded Apertures for Imaging via Nazarov's Theorem
Ganesh Ajjanagadde, Christos Thrampoulidis, Adam Yedidia +1
We characterize the fundamental limits of coded aperture imaging systems up to universal constants by drawing upon a theorem of Nazarov regarding Fourier transforms. Our work is pe…

Revealing hidden scenes by photon-efficient occlusion-based opportunistic active imaging
Feihu Xu, Gal Shulkind, Christos Thrampoulidis +4
The ability to see around corners, i.e., recover details of a hidden scene from its reflections in the surrounding environment, is of considerable interest in a wide range of appli…

Analysis and Optimization of Aperture Design in Computational Imaging
Adam Yedidia, Christos Thrampoulidis, Gregory Wornell
There is growing interest in the use of coded aperture imaging systems for a variety of applications. Using an analysis framework based on mutual information, we examine the fundam…
