DiffuserCam: Lensless Single-exposure 3D Imaging
TLDR
We present DiffuserCam, a lensless imager that uses a diffuser to encode the 3D intensity of volumetric objects into a single 2D image. Expand

Sparse Stochastic Processes and Discretization of Linear Inverse Problems
TLDR
We present a novel statistically-based discretization paradigm and derive a class of maximum a posteriori (MAP) estimators for solving ill-conditioned linear inverse problems. Expand

Data-Driven Design for Fourier Ptychographic Microscopy
TLDR
In this work, we learn LED source pattern designs that compress the many required measurements into only a few, with negligible loss in reconstruction quality or resolution. Expand

Bayesian Denoising: From MAP to MMSE Using Consistent Cycle Spinning
TLDR
We introduce a new approach for the implementation of minimum mean-square error (MMSE) denoising for signals with decoupled derivatives that are whitened with a finite-difference operator. Expand

Combined multi-plane phase retrieval and super-resolution optical fluctuation imaging for 4D cell microscopy
Super-resolution fluorescence microscopy provides unprecedented insight into cellular and subcellular structures. However, going ‘beyond the diffraction barrier’ comes at a price, since mostExpand
