Structure-Guided Self-Supervised Deep Despeckling of Coherent Images: From Polarimetric SAR to Medical OCT Images

Deep despeckling networks reach excellent accuracy when clean references exist, but coherent imaging systems never observe a speckle free scene, and self-supervised alternatives discard the spatial organization of the scene that classical region based filters exploit so effectively. This paper proposes a structure-guid...
