Researchers have developed Head-wise Temporal Token Merging (HTTM), a novel technique designed to accelerate the Visual Geometry Grounded Transformer (VGGT) model. VGGT is a groundbreaking model for 3D scene reconstruction, capable of inferring camera poses, depths, and geometry in a single pass. However, its global attention mechanism creates a latency bottleneck for large-scale reconstructions. HTTM addresses this by merging tokens based on individual attention heads, preserving feature uniqueness and leveraging spatial-temporal correlations to achieve up to a sevenfold increase in inference speed with minimal impact on performance.
