Super-Resolution and Denoising of Corneal B-Scan OCT Imaging Using Diffusion Model Plug-and-Play Priors
Yaning Wang, Jinglun Yu, Wenhan Guo +4
Optical coherence tomography (OCT) is pivotal in corneal imaging for both surgical planning and diagnosis. However, high-speed acquisitions often degrade spatial resolution and inc…
End-to-end reconstruction of OCT optical properties and speckle-reduced structural intensity via physics-based learning
Jinglun Yu, Yaning Wang, Wenhan Guo +3
Inverse scattering in optical coherence tomography (OCT) seeks to recover both structural images and intrinsic tissue optical properties, including refractive index, scattering coe…
Super-Resolution Optical Coherence Tomography Using Diffusion Model-Based Plug-and-Play Priors
Yaning Wang, Jinglun Yu, Wenhan Guo +2
We propose an OCT super-resolution framework based on a plug-and-play diffusion model (PnP-DM) to reconstruct high-quality images from sparse measurements (OCT B-mode corneal image…
Neural Inverse Scattering with Score-based Regularization
Yuan Gao, Wenhan Guo, Yu Sun
Inverse scattering is a fundamental challenge in many imaging applications, ranging from microscopy to remote sensing. Solving this problem often requires jointly estimating two un…
