ReDiffuse: Rotation Equivariant Diffusion Model for Multi-focus Image Fusion
arXiv CS.CV
•
ArXi:2603.21129v1 Announce Type: new Diffusion models have achieved impressive performance on multi-focus image fusion (MFIF). However, a key challenge in applying diffusion models to the ill-posed MFIF problem is that defocus blur can make common symmetric geometric structures (e.g., textures and edges) appear warped and deformed, often leading to unexpected artifacts in the fused images.
