Object Part-Aware Attention-Based Matching for Robust Visual Tracking

초록

In this paper, we propose a novel visual tracking method with a object part-aware attention-based matching (OPAM) mechanism, which leverages local-global attention to enhance visual tracking performance. Our method introduces three key components: (1) a local part-aware global self-attention mechanism that embeds rich contextual information among candidate regions, enabling the model to capture mutual dependencies and relationships effectively, (2) a local part-aware global cross-attention mechanism that injects target-specific information into candidate region features, improving the alignment and discrimination between the target and background, and (3) a global cross-attention mechanism that extracts object holistic information from the target-search feature context for further discriminability. By integrating these attention modules, our approach achieves robust feature aggregation and precise target localization. Extensive experiments on a large-scale tracking benchmark demonstrate that our method shows competitive performance metrics in both accuracy and robustness, particularly under challenging scenarios such as occlusion and appearance changes, while running at real-time speeds.
