Abstract

Computational Super-Resolution (CSR) in fluorescence microscopy aims to recover unobserved spatial frequencies by leveraging strong image priors. We introduce ResMatching, a guided conditional flow-matching framework that learns improved data-priors for CSR. Evaluated on four BioSR structures against seven baselines, ResMatching consistently achieves the best trade-off between fidelity and perceptual realism, especially under high noise. Moreover, it enables calibrated posterior sampling, providing pixel-wise uncertainty maps to identify unreliable predictions.

Key contributions: (1) A flow-matching framework for noise-resilient super-resolution, (2) Superior performance on diverse microscopy imaging tasks, (3) Efficient sampling from learned distributions for uncertainty calibration.
