RIDE: Retinex-Informed Decoupling for Exposing Concealed Objects

Chengyu Fang, Chunming He, Dingming Zhang, Fengyang Xiao, Jingjia Feng, Longxiang Tang, Rihan Zhang, Sina Farsiu

Retinex decomposition separates illumination from reflectance to widen the gap between foreground and background in concealed object segmentation.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Across diverse COS sub-tasks, the underlying physical processes systematically anti-correlate illumination and reflectance differences, yielding theoretical guarantees that Retinex decomposition preserves or strictly improves total foreground--background discriminability across the full physical regime, with anti-correlation maximizing the gain.

C2weakest assumption

The assumption that physical processes in COS tasks (camouflage, polyps, transparent objects, defects) systematically anti-correlate illumination and reflectance differences, as invoked to support the Discriminability Gap Theorem and the claimed guarantees.

C3one line summary

RIDE applies Retinex-based homogeneous decomposition to improve foreground-background discriminability in concealed object segmentation tasks across multiple domains.
