RoTA-Bench: Evaluating 3D Spatial Reasoning through Interactive Projection Alignment

The findings of RoTA-Bench highlight the challenge of converting visual evidence into precise 3D control, beyond recognizing or matching individual images, beyond recognizing or matching individual images.

RoTA-Bench: Evaluating 3D Spatial Reasoning through Interactive Projection Alignment

Can vision-language models turn 2D observations into 3D understanding that supports precise action? This requires inferring object geometry, anticipating the effects of rotation, and refining actions through visual feedback. We introduce RoTA-Bench to evaluate these abilities through interactive 3D-to-2D projection ali...

SocialOmni: Benchmarking Audio-Visual Social Interactivity in Omni Models

SocialOmni is introduced, an offline diagnostic benchmark that separates three turn-level decisions: identifying who is speaking, deciding when a designated participant should enter at an annotated query time, and determining how that participant should continue the dialogue.

One Ranking, Any Budget: Matryoshka Evidence-to-Context Frame Selection for Long-Video Understanding

Matryoshka Evidence-to-Context (MEC) Frame Selection is introduced, a training-free framework that builds a reusable sparse video index, discovers candidates through sparse probing and local zooming, and greedily constructs a position-adaptive ranking - early positions emphasize evidence; later positions progressively...

WaveZip: Wavelet-Driven Space-Time Decoupling for Video Token Condensation

WaveZip is proposed, a joint signal-frequency-domain framework for efficient video inference that requires no task-specific training and can be seamlessly integrated into off-the-shelf LVLMs to boost inference efficiency.
