A Primal-Dual Framework for Real-Time Dense RGB-D Scene Flow
Jaimez, Mariano; Souiai, Mohamed; González-Jiménez, Antonio Javier; Cremers, Daniel (IEEE, 2015-05)This paper presents the first method to compute dense scene flow in real-time for RGB-D cameras. It is based on a variational formulation where brightness constancy and geometric consistency are imposed. Accounting for ... -
A Robotic Experiment Toward Understanding Human Gas-Source Localization Strategies
This paper describes an experiment for gas-source localization with a human-teleoperated mobile robot devised to gather data on how humans search for odor-sources. To that end, more than 150 repetitions of the search ... -
A semantic-based gas source localization with a mobile robot combining vision and chemical sensing.
González-Monroy, Javier; Ruiz-Sarmiento, José Raúl; Moreno-Dueñas, Francisco Ángel; Meléndez-Fernández, Francisco; Galindo-Andrades, Cipriano; González-Jiménez, Antonio Javier[et al.] (MDPI, 2018-11-28)This paper addresses the localization of a gas emission source within a real-world human environment with a mobile robot. Our approach is based on an efficient and coherent system that fuses different sensor modalities ... -
A Tighter Relaxation for the Relative Pose Problem Between Cameras
García-Salguero, Mercedes; Briales Garcia, Jesus; González-Jiménez, Antonio Javier (Springer, 2022-04-06)This paper tackles the resolution of the Relative Pose problem with optimality guarantees by stating it as an optimization problem over the set of essential matrices that minimizes the squared epipolar error. We relax this ... -
Accurate Stereo Visual Odometry with Gamma Distributions
Point-based stereo visual odometry systems typically estimate the camera motion by minimizing a cost function of the projection residuals between consecutive frames. Under some mild assumptions, such minimization is ... -
