SECA-Net unifies CNN and Transformer features for salient object detection, effectively using edge cues to improve boundary accuracy and outperform existing methods.

Area of Science:

  • Computer Vision
  • Deep Learning
  • Image Processing

Background:

  • Hybrid multi-backbone architectures and edge cue utilization are key trends in salient object detection (SOD).
  • CNNs excel at local structures, while Transformers capture global dependencies, but feature discrepancies and boundary degradation pose challenges.
  • Effectively using edge cues without introducing false boundaries or leakages remains an open problem.

Purpose of the Study:

  • To present SECA-Net, a unified framework synergizing CNN and Transformer representations for salient object detection.
  • To address feature discrepancies between CNNs and Transformers and mitigate boundary-detail degradation during multi-scale fusion.
  • To leverage edge cues effectively for structural guidance, reducing texture-induced false contours and boundary leakages.

  • A dual-encoder structure extracts features, employing a level-wise feature interaction (LFI) module for discrepancy-aware fusion.
  • A semantic-aware edge refinement (SAER) module generates clean edge priors using high-level semantic guidance.
  • An edge-guided cross-attention feature aggregation (ECFA) module progressively injects refined edge priors into multi-scale decoding.

Main Results:

  • SECA-Net demonstrates superior performance against 19 state-of-the-art methods across five benchmark SOD datasets.
  • The proposed method achieved top rankings in Fβ and BDE metrics on all tested datasets.
  • A notable improvement of 1.54% in Fβ was observed on the DUTS-TE dataset.

Conclusions:

  • SECA-Net effectively bridges CNN-Transformer discrepancies and resolves structural degradation through its unified framework.
  • The framework successfully utilizes edge cues, alleviating boundary issues and improving salient object detection accuracy.
  • Experimental results validate SECA-Net's effectiveness and superiority in salient object detection tasks.
