Learning phase diversity for solving ill-posed inverse problems in imaging
Jasleen Birdi, Tamal Majumder, Debanjan Halder +2
Inverse problems in imaging are typically ill-posed and are usually solved by employing regularized optimization techniques. The usage of appropriate constraints can restrict the s…
True 3D reconstruction in digital holography
Jasleen Birdi, Sunaina, Mansi Butola +1
We examine the nature of the 3D image as obtained by replay (or back-propagation) of the object wave from the hologram recording plane to the original object volume. While recordin…
Polca SARA - Full polarization, direction-dependent calibration and sparse imaging for radio interferometry
Jasleen Birdi, Audrey Repetti, Yves Wiaux
New generation of radio interferometers are envisaged to produce high quality, high dynamic range Stokes images of the observed sky from the corresponding under-sampled Fourier dom…
Sparse interferometric Stokes imaging under polarization constraint (Polarized SARA)
Jasleen Birdi, Audrey Repetti, Yves Wiaux
We develop a novel algorithm for sparse Stokes parameters imaging in radio interferometry under the polarization constraint. The latter is a physical non-linear relation between th…
Non-convex optimization for self-calibration of direction-dependent effects in radio interferometric imaging
Audrey Repetti, Jasleen Birdi, Arwa Dabbech +1
Radio interferometric imaging aims to estimate an unknown sky intensity image from degraded observations, acquired through an antenna array. In the theoretical case of a perfectly…
A regularized tri-linear approach for optical interferometric imaging
Jasleen Birdi, Audrey Repetti, Yves Wiaux
In the context of optical interferometry, only undersampled power spectrum and bispectrum data are accessible. It poses an ill-posed inverse problem for image recovery. Recently, a…
