When Deep Learning Meets Data Alignment: A Review on Deep Registration Networks (DRNs)

no code implementations6 Mar 2020 Victor Villena-Martinez, Sergiu Oprea, Marcelo Saval-Calvo, Jorge Azorin-Lopez, Andres Fuster-Guillo, Robert B. Fisher

Recent advancements in machine learning could be a turning point in these issues, particularly with the development of deep learning (DL) techniques, which are helping to improve multiple computer vision problems through an abstract understanding of the input data.

Hybrid Multi-camera Visual Servoing to Moving Target

no code implementations6 Mar 2018 Hanz Cuevas-Velasquez, Nanbo Li, Radim Tylecek, Marcelo Saval-Calvo, Robert B. Fisher

A Master supervisor task selects between using the EtoH or the EinH, depending on the distance between the robot and target.

Three-dimensional planar model estimation using multi-constraint knowledge based on k-means and RANSAC

no code implementations3 Aug 2017 Marcelo Saval-Calvo, Jorge Azorin-Lopez, Andres Fuster-Guillo, Jose Garcia-Rodriguez

Plane model extraction from three-dimensional point clouds is a necessary step in many different applications such as planar object reconstruction, indoor mapping and indoor localization.
