AnyCalib: On-Manifold Learning for Model-Agnostic Single-View Camera Calibration
Javier Tirado-Garín, Javier Civera
We present AnyCalib, a method for calibrating the intrinsic parameters of a camera from a single in-the-wild image, that is agnostic to the camera model. Current methods are predom…
From Correspondences to Pose: Non-minimal Certifiably Optimal Relative Pose without Disambiguation
Javier Tirado-Garín, Javier Civera
Estimating the relative camera pose from correspondences between two calibrated views is a fundamental task in computer vision. This process typically involves two stage…
DAC: Detector-Agnostic Spatial Covariances for Deep Local Features
Javier Tirado-Garín, Frederik Warburg, Javier Civera
Current deep visual local feature detectors do not model the spatial uncertainty of detected features, producing suboptimal results in downstream applications. In this work, we pro…
Jacobian Computation for Cumulative B-Splines on SE(3) and Application to Continuous-Time Object Tracking
Javier Tirado, Javier Civera
In this paper we propose a method that estimates the continuous trajectories (orientation and translation) of the dynamic rigid objects present in a scene, from multiple RG…
