    SAM2-DFBCNet: A Camouflaged Object Detection Network Based on the Heira Architecture of SAM2 by Cao Yuan, Libang Liu, Yaqin Li, Jianxiang Li

    Published 2025-07-01
    “…Our network incorporates three key modules: (1) the Camouflage-Aware Context Enhancement Module (CACEM), which fuses local and global features through an attention mechanism to enhance contextual awareness in low-contrast scenes; (2) the Cross-Scale Feature Interaction Bridge (CSFIB), which employs a bidirectional convolutional GRU for the dynamic fusion of multi-scale features, effectively mitigating representation inconsistencies caused by complex textures and deformations; and (3) the Dynamic Boundary Refinement Module (DBRM), which combines channel and spatial attention mechanisms to optimize boundary localization accuracy and enhance segmentation details. Extensive experiments on three public datasets—CAMO, COD10K, and NC4K—demonstrate that SAM2-DFBCNet outperforms twenty state-of-the-art methods, achieving maximum improvements of 7.4%, 5.78%, and 4.78% in key metrics such as <i>S</i>-measure (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi>S</mi><mi>α</mi></msub></semantics></math></inline-formula>), <i>F</i>-measure (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi>F</mi><mi>β</mi></msub></semantics></math></inline-formula>), and mean <i>E</i>-measure (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi>E</mi><mi>ϕ</mi></msub></semantics></math></inline-formula>), respectively, while reducing the Mean Absolute Error (<i>M</i>) by 37.8%. …”
