Physics-Constrained Diffusion for Underwater Image Restoration with Spatially Varying Background Light.

Underwater image restoration is challenging due to light absorption and scattering, which cause color distortion, low contrast, and uneven illumination. Existing methods either ignore the underwater imaging process or rely on simplified assumptions, especially treating background light as a spatially uniform component,...

Virtual Consistency Model for All-in-One Image Restoration

All-in-one Image Restoration (AIR) seeks to address diverse degradations using a unified model trained only once. Existing methods often rely on degradation-specific guidance, leading to conflicting gradients during training. In contrast, diffusion models offer a promising alternative by operating in a high-noise space...
