Dynamic consistency under wide-angle omnidirectional transitions

Develop a method within the InSpatio-World spatiotemporal autoregressive framework to ensure multi-view consistency and spatiotemporal coherence of dynamic elements during wide-angle, omnidirectional view transitions.

Background

InSpatio-World integrates an implicit spatiotemporal cache with explicit geometry-aware constraints to enable real-time, controllable 4D roaming from a single video. While this approach provides strong structural anchors and supports large-scale displacement in static environments, its memory primarily captures structural information and does not persistently encode fine-grained textures in generated regions.

The authors note a remaining gap for dynamic content: during wide-angle, 360-degree transitions, maintaining multi-view consistency and spatiotemporal coherence of moving objects remains unresolved. Addressing this would extend the framework’s robustness from static scenes to complex dynamic environments with omnidirectional navigation.

Furthermore, while this explicit geometric scheme effectively supports large-scale displacement in static environments, ensuring the multi-view consistency and spatio-temporal coherence of dynamic elements during wide-angle, omnidirectional view transitions remains an open challenge.

PEGS assumes a rigid scene, so it can only score moving content by discarding it. The clearest next step is a constraint that ties all views to one scene at once: our hardest axis, which asks for stereo and temporal consistency together, is the one that does not yet improve.
