π3-LEGS: a lightweight and fast geometry system for long- sequence 3D reconstruction

This paper proposes π³-LEGS, an efficient geometric inference system designed for scalable long-sequence 3D reconstruction that maintains stable performance on thousand-frame sequences without runtime failures, highlighting its effectiveness in achieving a favorable accuracy efficiency trade-off for large-scale 3D reco...

Structure-Aware Robust Fine-Tuning: Defending Vision-Language-Action Robots Against Physical Attention Hijacking

Attention-Guided Semantic Disruption (AGSD), an Expectation-over-Transformation optimized printable patch that jointly concentrates action-to-vision attention on the patch and disrupts vision-language semantic alignment, yielding strong cross-task and cross-architecture transfer is proposed.
