P-PatchDiff: Progressive Patch Diffusion Models for Low-Light Image Enhancement

Recent advancements in low-light image enhancement have leveraged diffusion models for their strong ability to generate perceptually realistic, detailed images. Patch diffusion models further offer a promising solution to size-agnostic image restoration while improving efficiency. However, existing methods typically re...

Hierarchical Prompt Injector for Domain Generalization Segmentation

Considering the difficulty of learning spatially and semantically aware prompt injection, the Hierarchical Prompt Injector is proposed, which enables spatially adaptive prompt injection in foundation models and auxiliary supervision to align hierarchical prompts with their corresponding object regions is introduced.
