AAAI 2025 Paper

MambaPro is a novel multi-modal object ReID framework that integrates CLIP's pre-trained capabilities with state-of-the-art multi-modal aggregation techniques. Using Parallel Feed-Forward Adapters (PFA), Synergistic Residual Prompts (SRP), and the innovative Mamba Aggregation (MA) mechanism, it achieves robust performance with reduced computational complexity. MambaPro sets new standards in handling long sequences and missing modalities.

Introduction

Multi-modal object ReID leverages complementary data from diverse modalities (e.g., RGB, NIR, TIR) to overcome challenges like poor lighting and occlusion. MambaPro advances this field by:

1. PFA: Transferring CLIP's pre-trained knowledge to ReID tasks via parallel adapters.
2. SRP: Integrating modality-specific prompts with synergistic transformations.
3. MA: Efficiently modeling intra- and inter-modality interactions with linear complexity.

Contributions

• Introduced MambaPro, the first CLIP-based framework for multi-modal object ReID.
• Developed SRP for synergistic learning across modalities with residual refinements.
• Proposed MA, achieving linear complexity for long-sequence multi-modal interactions.
• Validated effectiveness on RGBNT201, RGBNT100, and MSVR310 benchmarks.

Note

• If you want to use a CLIP-based framework for multi-modal object ReID, DeMo is a better choice, the prompt/adapter tuning configuration in MambaPro is retained for users, besides, we provide detailed visualizations code in DeMo.
