ESCNet: Edge-Semantic Collaborative Network for Camouflaged Object Detection

Camouflaged object detection (COD) faces unique challenges where target boundaries are intrinsically ambiguous due to their textural similarity to backgrounds. Existing methods relying on single-modality features often produce fragmented predictions due to insufficient boundary constraints.To address this, we propose ESCNet with dynamically coupled edge-texture perception. Our framework introduces three core innovations that work in concert:1) Adaptive Edge-Texture Perceptor (AETP), which creates an edge prediction behaviour where edge and texture information are mutually reinforcing based on the multi-scale features of the image integrated with the global semantic context of the Transformer;2) Dual-Stream Feature Augmentor (DSFA), which dynamically adjusts the kernel sampling position according to the local texture complexity and edge orientation, thus accurately enhancing the feature information at fractal boundaries and amorphous texture locations;3) Multi-Feature Modulation Module (MFMM), which establishes incremental fine-grained improvements for feature calibration and model prediction through enhanced characterisation of edge perception and hierarchical integration of multiple textures. This interconnected system forms a feedback loop where enhanced representations of edge perception enhance model texture prediction and vice versa. Our ESCNet demonstrates significant performance advantages on all three authoritative datasets.
