  1. aArea of the mask (unit: pixel). Heartbeat signals were extracted from the bentire video (i.e. no filter of the half-heart mask generation was enabled), chighly varied region (the first two filters were enabled), dheart region (the first three filters were enabled) and ehalf-heart region (all filters were enabled)
