Learning-based Noise Component Map Estimation for Image Denoising
Sheyda Ghanbaralizadeh Bahnemiri, Mykola Ponomarenko, Karen Egiazarian
A problem of image denoising when images are corrupted by a non-stationary noise is considered in this paper. Since in practice no a priori information on noise is available, noise…
SSR-PR: Single-shot Super-Resolution Phase Retrieval based two prior calibration tests
Peter Kocsis, Igor Shevkunov, Vladimir Katkovnik +2
We propose a novel approach and algorithm based on two preliminary tests of the optical system elements to enhance the super-resolved complex-valued imaging. The approach is develo…
ADMM and Spectral Proximity Operators in Hyperspectral Broadband Phase Retrieval for Quantitative Phase Imaging
Vladimir Katkovnik, Igor Shevkunov, Karen Egiazarian
A novel formulation of the hyperspectral broadband phase retrieval is developed for the scenario where both object and modulation phase masks are spectrally varying. The proposed a…
