Eulerian video magnification is inspired by a model in fluid mechanics called Eulerian specification of the flow field. Let's consider a moving, fluid body, such as a river. The Eulerian specification describes the river's velocity at a given position and time. The velocity would be fast in the mountains in springtime and slow at the river's mouth in winter. Also, the velocity would be slower at a silt-saturated point at the river's bottom, compared to a point where the river's surface hits a rock and sprays. An alternative to the Eulerian specification is the Lagrangian specification, which describes the position of a given particle at a given time. A given bit of silt might make its way down from the mountains to the river's mouth over a period of many years and then spend eons drifting around a tidal basin.
