Human gait recognition using extraction and fusion of global motion features
(SPRINGER, 2011)
This paper proposes a novel computer vision approach that processes video sequences of people walking and then recognises those people by their gait. Human motion carries different information that can be analysed in various ...
Action recognition approaches with context and multi-scale motion awareness
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE CIÊNCIA DA COMPUTAÇÃOPrograma de Pós-Graduação em Ciência da ComputaçãoUFMG, 2022-07-29)
Embora tenhamos testemunhado um progresso substancial feito por abordagens de visão computacional na solução de problemas de classificação de imagens, detecção de objetos e estimativa de pose, para citar alguns, o ...
Bayesian Estimation of Turbulent Motion
(IEEE Computer Society, 2013-04)
Based on physical laws describing the multiscale structure of turbulent flows, this paper proposes a regularizer for fluid motion estimation from an image sequence. Regularization is achieved by imposing some scale invariance ...
Motion-based wave estimation: Small-scale tests with a crane-barge model
(ELSEVIER SCI LTDOXFORD, 2012)
This paper provides additional validation to the problem of estimating wave spectra based on the first-order motions of a moored vessel. Prior investigations conducted by the authors have attested that even a large-volume ...
Incipient motion of sediments in oscillatory flows of pseudoplastic fluids: Preliminary results
(Avestia Publishing, 2017)
Preliminary results of an experimental study on the incipient motion of granular, non-cohesive particles in a laminar oscillatory flow of water and power law fluids are presented in this paper. The threshold condition is ...
Earthquake magnitude calculation without saturation from the scaling of peak ground displacement
(Amer Geophysical Union, 2015)
GPS instruments are noninertial and directly measure displacements with respect to a
global reference frame, while inertial sensors are affected by systematic offsets—primarily tilting—that
adversely impact integration ...
The sparkling Universe: A scenario for cosmic void motions
(Oxford University Press, 2016-10)
Cosmic voids are prominent features of the Universe, encoding relevant information of the growth and evolution of structure through their dynamics. Here, we perform a statistical study of the global motion of cosmic voids ...
Directional Wave Spectrum Estimation Based on Vessel`s 1st-order Motions: Field Results
(INT SOC OFFSHORE POLAR ENGINEERS, 2009)
In this paper, 2 different approaches for estimating the directional wave spectrum based on a vessel`s 1st-order motions are discussed, and their predictions are compared to those provided by a wave buoy. The real-scale ...
Multiscale dynamics under the lens of permutation entropy
(Elsevier Science, 2020-12-01)
In this paper, we characterize multi-scaling dynamics by estimating the permutation entropy at different time lags. Numerical simulations generated from fractional Brownian motion were used to illustrate how this multiscale ...
