A Deep Generative Approach to Oversampling in Ptychography

no code implementations28 Jul 2022 Semih Barutcu, Aggelos K. Katsaggelos, Doğa Gürsoy

Traditional approaches with reduced overlap between scanning areas result in reconstructions with artifacts.

Compressive Ptychography using Deep Image and Generative Priors

no code implementations5 May 2022 Semih Barutcu, Doğa Gürsoy, Aggelos K. Katsaggelos

However, reconstructions with less number of scan points lead to imaging artifacts and significant distortions, hindering a quantitative evaluation of the results.

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.
