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.

Adaptive Illumination based Depth Sensing using Deep Superpixel and Soft Sampling Approximation

1 code implementation23 Mar 2021 Qiqin Dai, Fengqiang Li, Oliver Cossairt, Aggelos K Katsaggelos

The adaptive sparse depth sampling network is jointly trained with a fusion network of an RGB image and sparse depth, to generate optimal adaptive sampling masks.
