Full-body pose tracking under severe occlusions: the Top View Reprojection approach

Abstract

Marker-less articulated human body pose recovery and tracking is a challenging problem of great importance, with strong theoretical and practical implications. The recent introduction of low-cost depth cameras triggered a number of interesting new works, pushing forward the state of the art. However, despite the remarkable progress, estimating the body pose in realistic, complex scenarios is still an open research task. In this thesis we propose and develop a markerless model-based method to recover and track the full body pose, from RGB-D sequences, in arbitrary scenarios where users can freely enter or leave the scene, move, act and interact with other users or the environment. Our research focuses mainly on the problem of handling occlusions, either across body parts belonging to the same user, or across different users. At the same time, we attempt to tackle additional important issues encountered in the problem at hand, such as dealing with the large diversity of human bodies or t ...
