. The goal of COD (as figure) is to find the camouflaged objects that are similar to the background, while in SOD, that goal is to distinguish the most eye-catching objects from the background. Inspired by the human visual system, which first discerns the boundaries of ambiguous regions (i.e., hard regions) before delving into the semantic meaning, we propose a novel loss function, Spatial Coherence Loss (SCLoss), that uses the mutual response between adjacent pixels to suppress or emphasize the single-response of pixels.
