VISA: VLM-Guided Instance Semantic Auditing for 3D Occupancy World Models

Ruiqi Xian, Yuehan Xian, Jing Liang +2

The paper introduces VISA, a training-time method that uses a visual‑language model to audit and correct semantic labels of 3D voxel occupancy maps, improving object and rare‑class…

CalibFree: Self-Supervised View Feature Separation for Calibration-Free Multi-Camera Multi-Object Tracking

Ruiqi Xian, Deep Patel, Iain Melvin +3

Multi-camera multi-object tracking (MCMOT) faces significant challenges in maintaining consistent object identities across varying camera perspectives, particularly when precise ca…

GaussianSSC: Triplane-Guided Directional Gaussian Fields for 3D Semantic Completion

Ruiqi Xian, Jing Liang, He Yin +2

We present \emph{GaussianSSC}, a two-stage, grid-native and triplane-guided approach to semantic scene completion (SSC) that injects the benefits of Gaussians without replacing the…

FALCON: Future-Aware Learning with Contextual Object-Centric Pretraining for UAV Action Recognition

Ruiqi Xian, Xiyang Wu, Tianrui Guan +3

We introduce FALCON, a unified self-supervised video pretraining approach for UAV action recognition from raw RGB aerial footage, requiring no additional preprocessing at inference…

Bi-VLM: Pushing Ultra-Low Precision Post-Training Quantization Boundaries in Vision-Language Models

Xijun Wang, Junyun Huang, Rayyan Abdalla +3

We address the critical gap between the computational demands of vision-language models and the possible ultra-low-bit weight precision (bitwidth bits) we can use for highe…

On the Vulnerability of LLM/VLM-Controlled Robotics

Xiyang Wu, Souradip Chakraborty, Ruiqi Xian +6

In this work, we highlight vulnerabilities in robotic systems integrating large language models (LLMs) and vision-language models (VLMs) due to input modality sensitivities. While…
