Eulerian video magnification: a review
Indonesian Journal of Electrical Engineering and Computer Science, 2020 <p>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 movement under human skin and vibration of buildings. The human eye requires optical microscopes
