Speed up Eulerian Video Motion Magnification

open access: yesKurdistan Journal of Applied Research, 2017
A standard video can have small video motions that are difficult to see by naked eye because of it limited sensitivity. These hidden signals variation may have highly useful information that can be used in variety of applications fields such as ...

Lagrangian motion magnification with double sparse optical flow decomposition

open access: yesFrontiers 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 ...

Image Processing for Motion Magnification

open access: yesCoRR
Motion Magnification (MM) is a collection of relative recent techniques within the realm of Image Processing. The main motivation of introducing these techniques in to support the human visual system to capture relevant displacements of an object of interest; these motions can be in object color and in object location.

Motion magnification algorithms for video-based breathing monitoring

open access: yesBiomedical Signal Processing and Control, 2023
In this paper, we present two video processing techniques for contact-less estimation of the Respiratory Rate (RR) of framed subjects. Due to the modest extent of movements related to respiration in both infants and adults, specific algorithms to efficiently detect breathing are needed.

Event-Based Motion Magnification

open access: yes
Detecting and magnifying imperceptible high-frequency motions in real-world scenarios has substantial implications for industrial and medical applications. These motions are characterized by small amplitudes and high frequencies. Traditional motion magnification methods rely on costly high-speed cameras or active light sources, which limit the scope of

Learning-based Axial Video Motion Magnification

open access: yes
Video motion magnification amplifies invisible small motions to be perceptible, which provides humans with a spatially dense and holistic understanding of small motions in the scene of interest. This is based on the premise that magnifying small motions enhances the legibility of motions.

Detecting Damage Evolution of Masonry Structures through Computer-Vision-Based Monitoring Methods

open access: yesBuildings, 2022
Detecting the onset of structural damage and its progressive evolution is crucial for the assessment and maintenance of the built environment. This paper describes the application of a computer-vision-based methodology for structural health monitoring to

Figure–Ground Segmentation and Biological Motion Perception in Peripheral Visual Field

open access: yesBrain Sciences, 2023
Biological motion perception is a specific type of perceptual organization, during which a clear image of a moving human body is perceptually generated in virtue of certain core light dots representing the major joint movements.

Operational Deflection Shapes Magnification and Visualization Using Optical-Flow-Based Image Processing

open access: yesSensors, 2021
Much information can be derived from operational deflection shapes of vibrating structures and the magnification of their motion. However, the acquisition of deflection shapes usually requires a manual definition of an object’s points of interest, while ...
