Diffusion Models for Polarimetric Reconstruction of Circumstellar Environments in Correlated Speckle Noise
Quentin Villegas, Laurence Denneulin, Simon Prunet +3
High-contrast polarimetric imaging of circumstellar disks is severely limited by stellar leakage and speckle noise. Building upon the RHAPSODIE framework for polarimetric inverse p…

Diffusion models for polarimetric reconstruction of circumstellar environments
Quentin Villegas, Laurence Denneulin, Simon Prunet +5
In this paper, we propose an approach combining diffusion models and inverse problems for the reconstruction of circumstellar disk images. Our method builds upon the Rhapsodie fram…
