New prNet framework advances phase retrieval with data-driven stochastic refinement

By PulseAugur Editorial · [1 sources] ·

Researchers have developed prNet, a novel framework for phase retrieval that combines model-driven and data-driven techniques. This approach integrates Langevin dynamics with learned denoising and model-based updates to improve reconstruction fidelity and perceptual quality. The framework includes three variants: prNet-Small for a lightweight pipeline, prNet-Large for improved distortion metrics through parallel sampling, and prNet-Large-Adversarial for enhanced perceptual quality using an adversarially trained aggregation network. Experiments show prNet outperforms existing baselines in both fidelity and quality. AI

IMPACT Introduces a novel framework that improves phase retrieval accuracy and perceptual quality, potentially benefiting applications in imaging and signal processing.

    prNet: Data-Driven Phase Retrieval via Stochastic Refinement

    arXiv:2507.09608v3 Announce Type: replace-cross Abstract: Phase retrieval is an ill-posed inverse problem in which existing methods often struggle to balance reconstruction fidelity and perceptual quality. We propose a novel Langevin-based framework for phase retrieval that bridg…
