Large video processing using GPU programming
(IEEE (Institute of Electrical and Electronics Engineers)PE, 2023-04-25)
Currently, video cameras are used in many applications, from security to recognition mechanism, all based on the analysis of images and videos, these records are made in most cases for continuous periods of recording, which ...
Positive leader characteristics from high-speed video observations
(Amer Geophysical Union, 2008-04-01)
Based on analyses of high-speed video recordings of cloud-to-ground lightning in Brazil and the USA, the characteristics of positive cloud-to-ground (+CG) leaders are presented. The high frame rates permitted the average, ...

Validade de um procedimento utilizando câmeras digitais de baixo custo para realização dos testes de velocidade de corrida em 30 metros e do salto com contra movimento
(Universidade Federal de Minas GeraisUFMG, 2014-12-12)
This present study is aimed to examine the concurrent validity of the height of counter movement jump (SCM), and the time of the 30 meters speed test in straight line (V30), comparing low-cost equipment, digital cameras ...
Single camera time-resolved 3D tomographic reconstruction of a pulsed gas jet
(Springer, 2013-11)
Experimental characterization of micro-jets is challenging because of the small dimensions of the micro-nozzle. In this study, we propose a new technique to visualize the instantaneous 3D structure of a pulsed gas micro-jet. ...
