Video magnification in presence of large motions
2015 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2015Video magnification reveals subtle variations that would be otherwise invisible to the naked eye. Current techniques require all motion in the video to be very small, which is unfortunately not always the case. Tiny yet meaningful motions are often combined with larger motions, such as the small vibrations of a gate as it rotates, or the microsaccades ...

Efficient Motion Magnification
2016Video motion magnification (VMM) allows to amplify hardly visible changes in the video input sequence. It is possible to amplify breathing motion of hospital patients or oscillations of some mechanical element without need to connect measuring devices.

Video Minor Motion Magnification System for Telemedicine
2015 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery, 2015Telemedicine system requires video support in which many key information of patients is included such as pulse motion and skin color changes. But those motion are too small to be well perceived by the naked eye. In this paper we proposed a video minor motion magnification system that can magnify the minor motion of pulse of neck and wrist and magnify ...

Optimizing motion scaling and magnification in robotic surgery
Surgery, 2004Motion scaling is one possible advantage of robotic surgery. The aim of this study was to determine which scaling optimized precision and speed at different magnifications.Three levels of motion scaling were tested at each of 3 camera magnifications. Surgically nave subjects (n = 12) were randomized as to the order of magnification level testing (3.5x,

Motion Magnification Analysis for structural monitoring of ancient constructions
Measurement: Journal of the International Measurement Confederation, 2018 A new methodology for digital image processing, namely the Motion Magnification (MM), allows to magnify small displacements of large structures. MM acts like a microscope for motion in video sequences, but affecting only some groups of pixels.

Impairment Magnification During Dynamic Trunk Motions
Spine, 2000An examination of a group of patients with low back disorder and a group of healthy (asymptomatic) individuals asked to produce trunk motions under sincere and insincere experimental conditions. Trunk motion components were examined to determine which combination of motion components could best distinguish between sincere and insincere efforts.To ...

Motion magnification using the Hermite transform
SPIE Proceedings, 2015We present an Eulerian motion magnification technique with a spatial decomposition based on the Hermite Transform (HT). We compare our results to the approach presented in.1 We test our method in one sequence of the breathing of a newborn baby and on an MRI left ventricle sequence.

GPU-based video motion magnification
AIP Conference Proceedings, 2016Video motion magnification (VMM) allows people see otherwise not visible subtle changes in surrounding world. VMM is also capable of hiding them with a modified version of the algorithm. It is possible to magnify motion related to breathing of patients in hospital to observe it or extinguish it and extract other information from stabilized image ...

Computationally Efficient Face Spoofing Detection with Motion Magnification
2013 IEEE Conference on Computer Vision and Pattern Recognition Workshops, 2013For a robust face biometric system, a reliable anti-spoofing approach must be deployed to circumvent the print and replay attacks. Several techniques have been proposed to counter face spoofing, however a robust solution that is computationally efficient is still unavailable.
