The ability to analyse and predict the movement of people in crowded scenarios can be of fundamental importance for tracking across multiple cameras and interaction localisation. In this thesis, we propose a person re-identification method that takes into account the spatial loc…
Reconstructing the 3D geometry of scenes based on monocular image sequences is a long-standing problem in computer vision. Structure from motion (SfM) aims at a data-driven approach without requiring a priori models of the scene. When the scene is rigid, SfM is a well understood…
Image sequences with humans and human activities are everywhere. With the amount of produced and distributed data increasing at an unprecedented rate, there has been a lot of interest in building systems that can understand and interpret the visual data, and in particular detect…
