摘要:

基于远程光电容积脉搏波(rPPG)技术的非接触式心率测量方法主要面临两个方面的挑战:一是准确选取面部感兴趣区域(RoI);二是从长视频序列中准确理解rPPG的周期模式。针对现有工作中面部RoI定位不精准和未考虑到不同信号源之间的时间滞后性的问题,提出一个端到端的rPPG信号提取模型RppgMamba,用于非接触式心率测量。在该模型中,设计的具有交叉扫描机制的分层时空Mamba模块从多尺度的时空感受场中挖掘弱信号的空间感知关系,以自适应地定位面部RoI,从而避免受到背景和运动噪声等带来的干扰;而设计的频域细化模块在频域中进一步学习rPPG信号的准周期模式,以提高输出信号质量,同时结合相位补偿器对输出信号进行相位校正,减少固有时间滞后性带来的影响。实验结果表明,所提模型在三个公开数据集上获得了最佳的性能,验证了该模型对心率测量良好的精确度和适用性。

Abstract:

Non-contact heart rate measurement methods based on remote PhotoPlethysmoGraphy (rPPG) technology face two main challenges: the accurate selection of facial Regions of Interest (RoI), and the precise interpretation of periodic patterns in rPPG from long video sequences. To address the inaccurate localization of facial RoI in the existing works and the neglect of temporal lag among different signal sources, an end-to-end rPPG signal extraction model, named RppgMamba, was proposed for non-contact heart rate measurement. In the model, the hierarchical spatial-temporal Mamba module with cross-scan mechanism was designed to capture spatial perception relationships of weak signals from multi-scale spatial-temporal receptive fields, so as to localize facial RoI adaptively, thereby avoiding interference from background and motion noise. And the frequency-domain refinement module was designed to further learn the quasi-periodic patterns of rPPG signals in the frequency domain, which enhanced output signal quality and corrected phase shifts of the output signals combining with phase compensator, thereby reducing the impact of inherent temporal lag. Experimental results demonstrate that the proposed model achieves the best performance on three public datasets, confirming its high accuracy and applicability in heart rate measurement.
