A survey on learning approaches for Undirected Graphical Models. Application to scene object recognition
Ruiz-Sarmiento, José Raúl; Galindo-Andrades, Cipriano; González-Jiménez, Antonio Javier (Elsevier, 2017)
Probabilistic Graphical Models (PGMs) in general, and Undirected Graphical Models (UGMs) in particular, become suitable frameworks to capture and conveniently model the uncertainty inherent in a variety of problems. When ... -
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 ... -
