Learning-based Axial Video Motion Magnification [PDF]

open access: yesarXiv, 2023
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.

Motion capture is motion integration

open access: yesJournal of Vision, 2010
The phenomenon of “motion capture†has been described as a suppression of the motion of high spatial-frequency (SF) elements in favor of the motion of low SF components, allowing larger forms to capture their smaller features when they move (e.g., Ramachandran, 1990).

Nearest advocate: a novel event-based time delay estimation algorithm for multi-sensor time-series data synchronization

open access: yesEURASIP Journal on Advances in Signal Processing
Estimating time delays in event-based time-series is a crucial task in signal processing as it affects the data quality and is a prerequisite for many subsequent analyses.

Super Resolution with Kernel Estimation and Dual Attention Mechanism

open access: yesInformation, 2020
Convolutional Neural Networks (CNN) have led to promising performance in super-resolution (SR). Most SR methods are trained and evaluated on predefined blur kernel datasets (e.g., bicubic).

Brain-movement relationship during upper-limb functional movements in chronic post-stroke patients

open access: yesJournal of NeuroEngineering and Rehabilitation
Background Following a stroke, brain activation reorganisation, movement compensatory strategies, motor performance and their evolution through rehabilitation are matters of importance for clinicians.

Skiing quality analysis of recreational skiers based on IMU data and self-assessment

open access: yesFrontiers in Sports and Active Living
Alpine skiing is a popular sport in many countries and holds benefits in terms of health and well-being. At the same time alpine skiing is associated with a certain risk of accidents caused, among other things, by overestimating one’s own skiing skills ...

Motion compensation of motion vectors

open access: yesProceedings., International Conference on Image Processing, 2002
Motion compensation of image data has long been used for video compression. "Meta-motion" compensation, or motion compensation of motion vectors is presented as a new approach to data compression useful in very low bit rate (VLB) applications. Whereas present motion coding simply takes advantage of temporal redundancies among images, this new ...

Motion, Unit Dual Quaternion and Motion Optimization [PDF]

open access: yesarXiv, 2022
We introduce motions as real six-dimensional vectors. A motion means a rotation and a translation. We define a motion operator which maps unit dual quaternions to motions, and a UDQ operator which maps motions to unit dual quaternions. By these operators, we present the formulation of motion optimization, which is actually a real unconstrained ...

Motion streaks improve motion detection

open access: yesVision Research, 2007
A number of studies were conducted to determine whether motion-streaks assist motion extraction, and whether a purely motion-based model could account for any observed facilitation. A 3-frame global-motion stimulus was used. Signal dots were manipulated in order to control the strength of the motion-streak.

Collective motion [PDF]

open access: yes, 2001
Abstract The collective motion of various organisms like the flocking of birds (Fig. 6.1) [1], the swimming of schools of fish [2], and the motion of herds of quadrupeds, migrating bacteria (§4.1 ), ants [3] or pedestrians (§6.2) is a fascinating phenomenon catching our eyes when we observe our natural environment.
