\justifying
The coarse-to-fine strategy is an architecture that combines global prediction and
local refinement. This structure can decouple complex targets, first make rough
predictions for the overall area, and then refine the predictions through a variety
of means. According to different refinement methods, existing camouflage target
detection methods based on coarse-to-fine strategies can be divided into three
categories: camouflage target detection methods that use feature fusion refinement,
and camouflage target detection methods that use distraction mining to refine and
camouflaged target detection methods utilizing edge cue refinement.
