Generative DH-MBIR for real-time coherent imaging through turbulence

Digital Holography Model-Based Iterative Reconstruction (DHMBIR) jointly estimates atmospheric phase and target reflectance from noisy holography frames via Expectation-Maximization (EM). High wind speeds decorrelate consecutive frames fast enough to trap deterministic EM in local minima, and real-time wavefront correc...

Deep Pseudo-Proximal Map: A Self-Supervised Data-Fitting Agent for Iterative Reconstruction

Iterative algorithms for inverse imaging problems split reconstruction into alternating subproblems, one of which requires evaluating the data-fitting proximal map. In many practical cases, this proximal map has no analytic solution and so must be approximated by an inner loop solver at every iteration, compounding the...
