• Abstract: Developing robust multi-modal feature representations is crucial for enhancing object tracking performance. In pursuit of this objective, a novel X Modality Assisting Network (X-Net) is introduced, which explores the impact of the fusion paradigm by decoupling visual object tracking into three distinct levels, thereby facilitating subsequent processing. Initially, to overcome the challenges associated with feature learning due to significant discrepancies between RGB and thermal modalities, a plug-and-play pixel-level generation module (PGM) based on knowledge distillation learning is proposed. This module effectively generates the X modality, bridging the gap between the two patterns while minimizing noise interference. Subsequently, to optimize sample feature representation and promote cross-modal interactions, a feature-level interaction module (FIM) is introduced, integrating a mixed feature interaction transformer and a spatial dimensional feature translation strategy. Finally, to address random drifting caused by missing instance features, a flexible online optimization strategy called the decision-level refinement module (DRM) is proposed, which incorporates optical flow and refinement mechanisms. The efficacy of X-Net is validated through experiments on three benchmarks, demonstrating its superiority over state-of-the-art trackers. Notably, X-Net achieves performance gains of 0.47%/1.2% in the average of precise rate and success rate, respectively. Additionally, the research content, data, and code are pledged to be made publicly accessible at https://github.com/DZSYUNNAN/XNet.

  Cross-layer feature pyramid networks (CFPNs) have achieved notable progress in multi-scale feature fusion and boundary detail preservation for salient object detection. To address these challenges, we propose CFMD, a novel cross-layer feature pyramid network that introduces two key innovations. First, we design a context-aware feature aggregation module (CFLMA), which incorporates the state-of-the-art Mamba architecture to construct a dynamic weight distribution mechanism. Second, we introduce an adaptive dynamic upsampling unit (CFLMD) that preserves spatial details during resolution recovery.
