> Frequently Asked Questions

We have updated the V4V webpage with frequently asked questions. Please refer to the below FAQs.

Q1: How are the V4V ground truth physiological signals collected?

A: Details regarding the acquisition of data can be found in Section 2.2.3 in the paper: Multimodal Spontaneous Emotion Corpus for Human Behavior Analysis (link mentioned below). The ground truth device gives us a continuous BP signal. Following the signal acquisition, HR is calculated using an off-the-shelf software by computing peak-to-peak interval in the BP signal. (If you would like to read more about the off-the-shelf software, please visit the PDF - link mentioned below).
