Block diagram illustrating the split of data in the different groups. Separation by the clinical features: stroke patients and general group of patients, and by the device used to acquire the PPG signal. Group A1 – data from fPPG of stroke patients; group A2 – data from rPPG of stroke patients; group B – data from fPPG of general patients. The training (green boxes) and test (blue boxes) represent the split data by the three experiments (Exp) described in the next sections.
