Figure Lengend Snippet: a Exercising. b Rotation. c Talk. The estimated HR before and after correction, as well as the ground truth HR, are shown as blue, red, and black curves, respectively. The yellow polygon on the human face represents the glabella as the ROI. Above each facial video sequence, the subject code and MAE of HR estimation—averaged over the plane-orthogonal-to-skin (POS) , orthogonal matrix image transformation (OMIT) , chrominance-based (CHROM) , and local group invariance (LGI) algorithms–are presented.
