Blind source separation for imaging
Randy Bartels, Olivier Pinaud
This work is concerned with the problem of blind source separation and its applications to imaging. We first establish a theoretical result that we stated in our previous article o…

Analysis and extensions of the Multi-Layer Born method
Randy Bartels, Olivier Pinaud
Simulating scalar wave propagation in strongly heterogeneous media comes at a steep computational cost, and the widely used approach to simplification - split-step operators - sacr…

Speckle imaging with blind source separation and total variation deconvolution
Randy Bartels, Olivier Pinaud, Maxine Varughese
This work is concerned with optical imaging in strongly diffusive environments. We consider a typical setting in optical coherence tomography where a sample is probed by a collecti…
