EVENT-ADAPTIVE STATE TRANSITION AND GATED FUSION FOR RGB-EVENT OBJECT TRACKING
Event-Adaptive State Transition and Gated Fusion for RGB-Event Object Tracking
Existing Vision Mamba-based RGB-Event (RGBE) tracking methods suffer from using static state transition matrices, which fail to adapt to variations in event sparsity. This rigidity leads to imbalanced modeling—underfitting sparse event streams and overfitting dense ones—thus degrading cross-modal fusion robustness. These limitations hinder effective tracking in complex, dynamic environments.
We propose MambaTrack, a multimodal and efficient tracking framework built upon a Dynamic State Space Model (DSSM). It incorporates an event-adaptive state transition mechanism that dynamically modulates the state transition matrix based on event stream density, using a learnable scalar to govern state evolution. Additionally, a Gated Projection Fusion (GPF) module projects RGB features into the event feature space and generates adaptive gates from event density and RGB confidence scores to control fusion intensity, suppressing noise while preserving complementary information.
Executive Impact: Key Performance Metrics
MambaTrack achieves state-of-the-art performance on the FE108 and FELT datasets. Its lightweight design suggests potential for real-time embedded deployment, offering enhanced robustness and adaptability for RGB-Event tracking tasks. This method addresses critical challenges like motion blur, low-light conditions, and computational redundancy, making it highly valuable for autonomous driving, robotic navigation, and human-computer interaction.

Gated Projection Fusion (GPF) Mechanism
The GPF module projects RGB features into the event feature space via an MLP, then generates adaptive gating coefficients based on event density and RGB confidence. This mechanism precisely controls fusion intensity, effectively suppressing noise while preserving complementary information and enabling bidirectional cross-modal weighted fusion.
