AB  - Binary segmentation tasks in computer vision exhibit diverse appearance distributions and complex boundary characteristics. To address the limited generalization and adaptability of existing models across heterogeneous tasks, we propose Abel-Net, an Aggregated Bilateral Edge Localization Network designed as a universal framework for multi-task binary segmentation. Abel-Net integrates global and local contextual cues to enhance feature learning and edge precision. Specifically, a multi-scale feature pyramid fusion strategy is implemented via an Aggregated Skip Connection (ASC) module to strengthen feature adaptability, while the Edge Dual Localization (EDL) mechanism performs coarse-to-fine refinement through edge-aware supervision. Additionally, Edge Attention (EA) and Edge Fusion Attention (EFA) modules prioritize edge-critical regions and facilitate accurate boundary alignment. Extensive experiments on nine diverse binary segmentation tasks demonstrate that Abel-Net performs comparably to or surpasses state-of-the-art task-specific networks, exhibiting strong adaptability to a wide range of visual perception challenges.
