Magnified Movements - Using Eulerian Video Magnification with Cultural Heritage Objects


This site describes the ongoing research using Eulerian video magnification (EVM) to investigate the behavior of paper and other materials.  EVM allows researchers to see movement that is not visible to the human eye alone and we have used it to show how paper moves as it is exposed to fluctuating relative humidity.  Much of what we have discovered is surprising.  The movement does not tend to be even and gradual, rather one side of a sheet of paper can behave radically differently than the other side.  At times pressure seems to build and then suddenly release.  As expected, different types of paper exhibit very different characteristics.

To use this site effectively, please read through the Project Narrative for an overall description of our objectives, working methods, problems and solutions.  The Video Library shows the objects we filmed and gives information about the conditions.  We will be adding to the video library and each new project will be described in the Project Narrative.  The Technical Guide has a user manual for the technical workflow including specifications for photographic and computer equipment.

EVM is a technique and tool developed by The Massachusetts Institute of Technology Computer Science and Artificial Intelligence Laboratory and QuantaResearch Cambridge, Inc.  It uses spatial decomposition and temporal filtering applied to video sequences to amplify subtle variations in the signal, allowing researchers to view movements that are not visible with the human eye alone.  To learn more aboutEulerian Video Magnification or acquire the program’s source code, visit
