Noninvasive Free Flap Monitoring Using Eulerian Video Magnification [PDF]
Case Reports in Otolaryngology, 2016 Eulerian Video Magnification (EVM) can enhance subtle changes in videos to reveal what was once invisible to the naked eye. In this proof of concept study, we investigated using EVM as a novel form of free flap monitoring.

Non-invasive measurements of respiration and heart rate across wildlife species using Eulerian Video Magnification of infrared thermal imagery [PDF]
BMC Biology, 2023 Background An animal’s metabolic rate, or energetic expenditure, both impacts and is impacted by interactions with its environment. However, techniques for obtaining measurements of metabolic rate are invasive, logistically difficult, and costly.

Eulerian video magnification for revealing subtle changes in the world [PDF]
ACM Transactions on Graphics, 2012 Our goal is to reveal temporal variations in videos that are difficult or impossible to see with the naked eye and display them in an indicative manner. Our method, which we call Eulerian Video Magnification, takes a standard video sequence as input, and applies spatial decomposition, followed by temporal filtering to the frames.
