TAC-Diff: Texture-Anchored Color Diffusion for Low-Light Image Enhancement

Low-light image enhancement aims to improve images captured under poor illumination by restoring texture details and correcting color and contrast. While diffusion-based models have demonstrated powerful generative capabilities and significant progress in this task, existing approaches face two empirical challenges. Fi...

Weakly supervised semantic segmentation (WSSS) with image-level labels is largely limited by the reliability of dense seed supervision. Existing CAM- and CLIP-based methods provide complementary localization cues, but their predictions are biased in different ways: classification-oriented cues are usually precise but i...
