Abstract
Systems and methods for training remote photoplethysmography ('PPG') models that outputs a subject PPG signal based on a subject video clip of a subject are described herein. The system may have a processor and a memory in communication with the processor. The memory may include a training module having instructions that, when executed by the processor, cause the processor to train the remote PPG model in a self-supervised contrastive learning manner using an unlabeled video clip having a sequence of images of a face of a person.
