Seeing the unseen: Could Eulerian video magnification aid clinician detection of subclinical Parkinson’s tremor? [PDF]
Journal of Clinical Neuroscience, 2020 Eulerian magnification amplifies very small movements in video, revealing otherwise invisible motion. This raises the possibility that it could enable clinician visualisation of subclinical tremor using a standard camera. We tested whether Eulerian magnification of apparently atremulous hands reveals a Parkinsonian tremor more frequently in Parkinson's

Phase-based video motion processing [PDF]
ACM Transactions on Graphics, 2013 We introduce a technique to manipulate small movements in videos based on an analysis of motion in complex-valued image pyramids. Phase variations of the coefficients of a complex-valued steerable pyramid over time correspond to motion, and can be ...

Computer Vision Technologies in Movement Disorders: A Systematic Review. [PDF]
Mov Disord Clin PractAbstract Background Evaluation of movement disorders primarily relies on phenomenology. Despite refinements in diagnostic criteria, the accuracy remains suboptimal. Such a gap may be bridged by machine learning and video technology, which permit objective, quantitative, non‐invasive motor analysis.

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 ...

A Comparative Evaluation of Heart Rate Estimation Methods using Face Videos [PDF]
, 2020 This paper presents a comparative evaluation of methods for remote heart rate estimation using face videos, i.e., given a video sequence of the face as input, methods to process it to obtain a robust estimation of the subjects heart rate at each moment ...

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.

Motion magnification in coronal seismology [PDF]
, 2016 We introduce a new method for the investigation of low-amplitude transverse oscillations of solar plasma non-uniformities, such as coronal loops, individual strands in coronal arcades, jets, prominence fibrils, polar plumes, and other contrast features ...
