Developed approach for phase-based Eulerian video magnification
TELKOMNIKA (Telecommunication Computing Electronics and Control), 2020 This paper proposes a modification approach for phased-based EVM in order to reduce the processing time without effect the quality of the magnified video. The proposed approach applies a resizing process on the input video using Lanczos-3 algorithm.

Eulerian Video Magnification Adaptation for Live Cell Microscopy Analysis
, 2019 In this paper an adaptation of the Eulerian Video Magnification technique is described for use with .TIFF files produced by a photo-conversion time lapse protocol for live cell microscopy, specifically for research into Acquired Immune Deficiency Syndrome.

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

Lagrangian motion magnification with double sparse optical flow decomposition
Frontiers in Applied Mathematics and Statistics, 2023 Microexpressions are fast and spatially small facial expressions that are difficult to detect. Therefore, motion magnification techniques, which aim at amplifying and hence revealing subtle motion in videos, appear useful for handling such expressions ...

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.

Visualization of Physiological Oscillations with Eulerian Video Magnification
The FASEB Journal, 2015 Researchers at MIT developed Eulerian Video Magnification (EVM) software that uses temporal and spatial filtering to magnify subtle changes in the environment (Wu et.al.). EVM may provide a unique method for the visualization of low frequency human physiological oscillations.
