New theory and algorithms advance coherent imaging techniques

Researchers have developed a new theoretical framework and algorithms for multilook coherent imaging, a technique used in applications like digital holography and synthetic aperture radar. The paper provides the first theoretical upper bound on the Mean Squared Error (MSE) for maximum likelihood estimators under the deep image prior hypothesis. The proposed algorithms enhance performance by incorporating the Newton-Schulz algorithm for matrix inversions and a bagging strategy to reduce projection errors, achieving state-of-the-art results.
