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.

Eulerian video magnification and analysis [PDF]
Communications of the ACM, 2016 The world is filled with important, but visually subtle signals. A person's pulse, the breathing of an infant, the sag and sway of a bridge---these all create visual patterns, which are too difficult to see with the naked eye. We present Eulerian Video Magnification, a computational technique for visualizing subtle color and motion

Visualization of small vibrations inside an MRI scanner using video motion amplification. [PDF]
Med PhysAbstract Background Diffusion‐weighted magnetic resonance imaging (DW‐MRI) acquisition requires the application of strong magnetic field gradients, which can induce mechanical vibrations in tissues or phantoms, potentially leading to signal loss or degradation.

An Efficient Eulerian Video Magnification Technique for Micro-biology Applications [PDF]
Radioengineering, 2017 The micro-biology videos often contain motions of particles which are not visible to naked eye. Therefore an efficient motion magnification technique is required to magnify these motions.

Amplitude-Based Filtering for Video Magnification in Presence of Large Motion
Sensors, 2018 Video magnification reveals important and informative subtle variations in the world. These signals are often combined with large motions which result in significant blurring artifacts and haloes when conventional video magnification approaches are used.
