  We present SAFE, a novel color constancy framework for pure-color scenes with (1) a scene-aware feature modulation network and (2) the Learned Color Space (LCS) that directly addresses the chromaticity collapse problem when scene color distributions become too uniform.

  We present BOCCHI, a real-captured local motion blur detection benchmark of 633 pixel-annotated images featuring textured blurred regions that defeat gradient-based shortcuts. We also propose MSDCT-UNet, a frequency-aware encoder–decoder that reads blur in the DCT domain via multi-scale DCT attention and FiLM modulation.
