Optical Flow as a Tool for Cardiac Motion Estimation
(INSTITUTE OF ELECTRICAL AND ELECTRONICS ENGINEERS INC., 2015-07-14)
A sparse based algorithm for optical flow estimation is presented and compared with several classical optical flow estimation algorithms. The comparison is performed using several video sequences available from the Middlebury ...
Finger kinematic modeling and real-time hand motion estimation
(SpringerNew YorkEUA, 2007)
High proper motion stars with declinations between −30° and −40° , and right ascensions between 00 h and 10 h 40m
(2001)
Proper motions, positions, nding charts and magnitudes are given for 147 newly discovered stars with
proper motions larger than 0.15 arcsec/year. They were found in a search for high proper motion stars carried out
in ...
Conditional filters for image sequence-based tracking - application to point tracking
(Institute of Electrical and Electronics Engineers, 2005-01)
A new conditional formulation of classical filtering methods is proposed. This formulation is dedicated to image sequence-based tracking. These conditional filters allow solving systems whose measurements and state ...
Ground Motion Correlations from Recorded Mexican Intermediate-depth, Intraslab Earthquakes
(2021)
Predictive models to estimate correlation coefficients between peak ground acceleration, peak ground velocity, and spectral acceleration residuals for Mexican intermediate-depth, intraslab earthquakes recorded on rock sites ...
Odometria visual baseada em técnicas de structure from motion
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia ElétricaAutomação e Sistemas; Engenharia de Computação; Telecomunicações, 2011-02-15)
Visual Odometry is the process that estimates camera position and orientation based solely on images and in features (projections of visual landmarks present in the scene)
extraced from them. With the increasing advance ...
An Empirical Study of Exhaustive Matching for Improving Motion Field Estimation
(MDPI, 2018)
Optical flow is defined as the motion field of pixels between two consecutive images. Traditionally, in order to estimate pixel motion field (or optical flow), an energy model is proposed. This energy model is composed of ...
Multiple motion encoding in phase-contrast MRI: A general theory and application to elastography imaging
(Elsevier, 2022)
While MRI allows to encode the motion of tissue in the magnetization's phase, it remains yet a challenge to obtain high fidelity motion images due to wraps in the phase for high encoding efficiencies. Therefore, we propose ...
