Vision-language models struggle with fine-grained thermal activity recognition for robots

By PulseAugur Editorial · [1 sources] ·

A new study published on arXiv investigates the performance of vision-language models (VLMs) when applied to thermal imagery for human activity understanding in human-robot interaction (HRI). The research found that while these models can identify general activity categories, they struggle with recognizing fine-grained actions like coughing or yawning, often hallucinate events, and produce inaccurate timelines. The study evaluated seven VLMs, including those designed for robotics, and found that simple preprocessing and additional reasoning provided only limited improvements, highlighting reliability concerns for practical robotic applications.
