摘要:

心率是最重要的健康指标之一,可用于调查和获得对各种人体生理和心理信息的直觉。因此,在没有基于接触的传感器的约束的情况下估计心率本身是一个非常有吸引力的研究领域,因为它能够在更广泛的场景中进行健康监测。因此,已经开发了从经典图像处理到卷积深度学习模型和架构的用于基于相机的心率估计的各种技术。这些研究工作的核心在于健康和视觉数据采集、清理、转换和注释。在本文中,我们讨论了如何准备数据的任务,开发或测试的算法或机器学习模型的心率估计从图像的面部区域。准备的数据包括摄像机帧以及来自心电图传感器的传感器读数。建议的管道分为四个主要步骤,即删除错误数据,帧和心电图时间戳去抖动,信号去噪和滤波,帧注释创建。我们的主要贡献是一种新的技术,消除抖动的健康传感器和相机的时间戳和方法,以准确的时间对齐视觉帧和心电图传感器数据,这也适用于其他类型的传感器。

英文摘要:

Heart rate is one of the most vital health metrics which can be utilized to investigate and gain intuitions into various human physiological and psychological information. Estimating heart rate without the constraints of contact-based sensors thus presents itself as a very attractive field of research as it enables well-being monitoring in a wider variety of scenarios. Consequently, various techniques for camera-based heart rate estimation have been developed ranging from classical image processing to convoluted deep learning models and architectures. At the heart of such research efforts lies health and visual data acquisition, cleaning, transformation, and annotation. In this paper, we discuss how to prepare data for the task of developing or testing an algorithm or machine learning model for heart rate estimation from images of facial regions. The data prepared is to include camera frames as well as sensor readings from an electrocardiograph sensor. The proposed pipeline is divided into four main steps, namely removal of faulty data, frame and electrocardiograph timestamp de-jittering, signal denoising and filtering, and frame annotation creation. Our main contributions are a novel technique of eliminating jitter from health sensor and camera timestamps and a method to accurately time align both visual frame and electrocardiogram sensor data which is also applicable to other sensor types.
