The team investigated whether Eularian Video Magnification (EVM) had practical applications for the conservation of cultural materials. Eulerian Video Magnification (EVM) is an open-source tool originally developed by MIT Computer Science and Artificial Intelligence Lab for medical monitoring environments. EVM can show movement that is not visible to the naked human eye such as a heartbeat within a chest. Our goal was to capture movement within objects as they shifted from one relative humidity (RH) to another.

The team produced a website that features some of the videos we made, serves as a users manual for applying EVM to conservation, lists materials used, and will be updated periodically. We found the EVM is a useful technique, and one that can be adopted with minimal cost or technical expertise. We will continue to explore the technique and publish our findings on our website Magnified Movements.
