Improved Imaging by Invex Regularizers with Global Optima Guarantees
Samuel Pinilla, Tingting Mu, Neil Bourne +1
Image reconstruction enhanced by regularizers, e.g., to enforce sparsity, low rank or smoothness priors on images, has many successful applications in vision tasks such as computer…
On design of hybrid diffractive optics for achromatic extended depth-of-field (EDoF) RGB imaging
Seyyed Reza Miri Rostami, Samuel Pinilla, Igor Shevkunov +2
A hybrid imaging system is a simultaneous physical arrangement of a refractive lens and a multilevel phase mask (MPM) as a diffractive optical element (DOE). The favorable properti…
Power-Balanced Hybrid Optics Boosted Design for Achromatic Extended-Depth-of-Field Imaging via Optimized Mixed OTF
Seyyed Reza Miri Rostami, Samuel Pinilla, Igor Shevkunov +2
The power-balanced hybrid optical imaging system is a special design of a diffractive computational camera, introduced in this paper, with image formation by a refractive lens and…
Exact Crystalline Structure Recovery in X-ray Crystallography from Coded Diffraction Patterns
Samuel Pinilla, Jorge Bacca, Cesar Vargas +2
X-ray crystallography (XC) is an experimental technique used to determine three-dimensional crystalline structures. The acquired data in XC, called diffraction patterns, is the Fou…
Frequency-Resolved Optical Gating Recovery via Smoothing Gradient
Samuel Pinilla, Tamir Bendory, Yonina C. Eldar +1
Frequency-resolved optical gating (FROG) is a popular technique for complete characterization of ultrashort laser pulses. The acquired data in FROG, called FROG trace, is the Fouri…
SPRSF: Sparse Phase Retrieval via Smoothing Function
Samuel Pinilla, Jorge Bacca, Henry Arguello
Phase retrieval (PR) is an ill-conditioned inverse problem which can be found in various science and engineering applications. Assuming sparse priority over the signal of interest,…
