Action selection for robotic manipulation of deformable objects
(ESF-JSPS, 2008)
Text en actes de congrés
Accés obertThis paper deals with the manipulation of planar deformable objects for typical service robot applications. Specifically, we present a system that straightens pieces of cloth from any arbitrary initial wrinkle condition ... -
Action selection for single-camera SLAM
(2010)
Article
Accés obertA method for evaluating, at video rate, the quality of actions for a single camera while mapping unknown indoor environments is presented. The strategy maximizes mutual information between measurements and states to help ... -
Active Appearance Models for People Recognition with a RGB-D Sensor
(Universitat Politècnica de Catalunya, 2014-06)
Projecte Final de Màster Oficial
Accés restringit per decisió de l'autorActive Appearance Models (AAMs) is a computer vision procedure for statistical matching of object shape and appearance between images. The present work will analyze how AAMs can be employed with RGB-Depth technology, so ... -
Active camera calibration for robotic systems
(Universitat Politècnica de Catalunya, 2016)
Projecte Final de Màster Oficial
Accés obert
