Interferometric Image Reconstruction using Closure Invariants and Machine Learning
Nithyanandan Thyagarajan, Lucas Hoefs, O. Ivy Wong
Interferometric closure invariants encode calibration-independent details of an object's morphology. Excepting simple cases, a direct backward transformation from closure invariant…
