Invisible Color Variations of Facial Erythema: A Novel Early Marker for Diabetic Complications?

Journal of Diabetes Research, Volume 2019, Issue 1, 2019., 2019
Aim. (1) To quantify the invisible variations of facial erythema that occur as the blood flows in and out of the face of diabetic patients, during the blood pulse wave using an innovative image processing method, on videos recorded with a conventional digital camera and (2) to determine whether this “unveiled” facial red coloration and its periodic ...

Eulerian video magnification: a review

, 2020
Many important subtle changes in the environment are invisible to the naked human eyes. These subtle changes occur because of colour variations, such as blood flow in a human face that leads to face colour change, or motion variations, such as vena ...

Examining in vivo tympanic membrane mobility using smart phone video-otoscopy and phase-based Eulerian video magnification [PDF]

, 2017
The tympanic membrane (TM) is the bridging element between the pressure waves of sound in air and the ossicular chain. It allows for sound to be conducted into the inner ear, achieving the human sense of hearing. Otitis media with effusion (OME, commonly
