Improving Acquisition Speed of X-Ray Ptychography through Spatial Undersampling and Regularization

no code implementations20 May 2021 Prasan Shedligeri, Florian Schiffers, Semih Barutcu, Pablo Ruiz, Aggelos K Katsaggelos, Oliver Cossairt

To avoid the ill-posedness, we investigate the effect of regularizing the phase retrieval algorithm with image priors for various overlap ratios between the neighboring diffraction patterns.

A Unified Framework for Compressive Video Recovery from Coded Exposure Techniques

1 code implementation11 Nov 2020 Prasan Shedligeri, Anupama S, Kaushik Mitra

Most recently, a Coded-2-Bucket camera has been proposed that can acquire two compressed measurements in a single exposure, unlike previously proposed coded exposure techniques, which can acquire only a single measurement.
