Abstract

The paper explores the limitations of Vision-Language Models (VLMs) in remote physiological measurement and proposes a new framework to address these challenges.

Reality Card

Core Claim

The proposed VITAL framework improves cross-domain estimation performance on multiple rPPG datasets while maintaining the general visual understanding capability of VLMs.

Method / Result

VITAL enhances generative heart rate estimation reliability through structured numerical alignment.

Limitations

The paper does not specify the authors or provide details on the reproducibility of the experiments.
