I was pointed to an awesome piece of research titled “Eulerian Video Magnification for Revealing Subtle Changes in the World.”
They have developed algorithms that allow them to amplify subtle changes in videos (color, movement) … and select desired frequencies at that. They have an awesome demonstration video:
Arstechnica has a nice piece on how to do science fraud and minimizing the risk of being caught. 😛
