GHOST framework slashes 3D reconstruction cache needs

By PulseAugur Editorial · [1 sources] ·

Researchers have developed GHOST, a new framework designed to manage the memory cache for streaming 3D reconstruction from long video sequences. This training-free method uses the model's own 3D geometry outputs to decide which data tokens to evict, addressing the memory bottleneck issue. GHOST employs a hierarchical scoring system, a privilege mechanism for critical tokens, and layer-wise budget allocation to optimize cache usage. The framework significantly reduces KV cache size and speeds up inference while maintaining high reconstruction quality. AI

IMPACT Enables more efficient processing of long video sequences for 3D reconstruction, potentially improving real-time applications.

    GHOST: Geometry-Hierarchical Online Streaming Token Eviction for Efficient 3D Reconstruction

    Streaming 3D reconstruction from long monocular video sequences requires maintaining a key-value (KV) cache that grows linearly with sequence length, creating a severe memory bottleneck. Existing approaches either truncate the cache to a fixed set of anchor frames, leading to rec…
