Applied Optics, 2017 Most LADAR (laser radar, LIDAR) imaging systems use pixel-basis sampling, where each azimuth and elevation resolution element is uniquely sampled and recorded. We demonstrate and examine alternative sampling and post-detection processing schemes where recorded measurements are made in alternative bases that are intended to reduce system power ...

Motion correction and volumetric reconstruction for fetal functional magnetic resonance imaging data
NeuroImage, 2022 Motion correction is an essential preprocessing step in functional Magnetic Resonance Imaging (fMRI) of the fetal brain with the aim to remove artifacts caused by fetal movement and maternal breathing and consequently to suppress erroneous signal ...

Computational temporal ghost imaging [PDF]
, 2016 Ghost imaging is a fascinating process, where light interacting with an object is recorded without resolution, but the shape of the object is nevertheless retrieved, thanks to quantum or classical correlations of this interacting light with either a ...

BlindNet: an untrained learning approach toward computational imaging with model uncertainty
Holography, Diffractive Optics, and Applications XI, 2021 The solution of an inverse problem in computational imaging (CI) often requires the knowledge of the physical model and/or the object. However, in many practical applications, the physical model may not be accurately characterized, leading to model ...
