VideoMamba: State Space Model for Efficient Video Understanding
It provides a scalable and efficient solution for video understanding tasks, addressing bottlenecks in existing methods, though it appears incremental as an adaptation of Mamba to video.
This work tackles the challenges of local redundancy and global dependencies in video understanding by adapting the Mamba state space model to the video domain, resulting in VideoMamba, which demonstrates scalability without extensive pretraining, sensitivity to fine-grained motions, superiority in long-term understanding, and multi-modal compatibility.
Addressing the dual challenges of local redundancy and global dependencies in video understanding, this work innovatively adapts the Mamba to the video domain. The proposed VideoMamba overcomes the limitations of existing 3D convolution neural networks and video transformers. Its linear-complexity operator enables efficient long-term modeling, which is crucial for high-resolution long video understanding. Extensive evaluations reveal VideoMamba's four core abilities: (1) Scalability in the visual domain without extensive dataset pretraining, thanks to a novel self-distillation technique; (2) Sensitivity for recognizing short-term actions even with fine-grained motion differences; (3) Superiority in long-term video understanding, showcasing significant advancements over traditional feature-based models; and (4) Compatibility with other modalities, demonstrating robustness in multi-modal contexts. Through these distinct advantages, VideoMamba sets a new benchmark for video understanding, offering a scalable and efficient solution for comprehensive video understanding.
