HTTM: Head-wise Temporal Token Merging for Faster VGGT

arXiv — cs.CVThursday, November 27, 2025 at 5:00:00 AM
  • The introduction of Head-wise Temporal Token Merging (HTTM) aims to enhance the efficiency of the Visual Geometry Grounded Transformer (VGGT) by addressing latency issues associated with global attention layers during 3D scene reconstruction. This method allows for a more effective merging of tokens, preserving their unique features and improving the model's representational capabilities.
  • This development is significant as it represents a training-free approach to optimizing VGGT, potentially leading to faster processing times and improved performance in reconstructing large-scale 3D scenes, which is crucial for applications in computer vision and robotics.
  • The advancement of HTTM reflects a growing trend in the field of artificial intelligence towards developing scalable and efficient models that can handle complex tasks. This aligns with other recent innovations in 3D scene representation and reconstruction, indicating a concerted effort to enhance computational efficiency while maintaining accuracy across various applications, including assistive navigation and dynamic scene understanding.

Emergent Outlier View Rejection in Visual Geometry Grounded Transformers
PositiveArtificial Intelligence
A recent study has revealed that feed-forward 3D reconstruction models, such as VGGT, can inherently distinguish noisy images, which traditionally hinder reliable 3D reconstruction from in-the-wild image collections. This discovery highlights a specific layer within the model that exhibits outlier-suppressing behavior, enabling effective noise filtering without explicit mechanisms for outlier rejection.
AVGGT: Rethinking Global Attention for Accelerating VGGT
PositiveArtificial Intelligence
A recent study titled 'AVGGT: Rethinking Global Attention for Accelerating VGGT' investigates the global attention mechanisms in models like VGGT and π3, revealing their roles in multi-view 3D performance. The authors propose a two-step acceleration scheme to enhance efficiency by modifying early global layers and subsampling global attention. This approach aims to reduce computational costs while maintaining performance.
