A Novel Approach for Fast Action Recognition using Simple Features (2008)

Ragheb, Hossein, Velastin, Sergio, Remagnino, Paolo, Ellis, Tim

We propose a new method for human action recognition from video streams that is fast and robust to random noise, partial occlusions and large changes in camera views. We extract features in the...

Real-time ghost removal for foreground segmentation methods (2008)

Yin, Fei, Makris, Dimitrios, Velastin, Sergio

Among all the challenges for foreground detection, we focus on detection of ghosts caused by the starting or stopping of objects. We propose a fast and effective method for ghost detection that...

Independent Viewpoint Silhouette-based Human Action Modelling and Recognition (2008)

Orrite, Carlos, Martínez, Francisco, Herrero, Elías, Ragheb, Hossein, Velastin, Sergio

This paper addresses the problem of silhouette-based human action modelling and recognition independently of the camera point of view. Action recognition is carried out by comparing a 2D motion...

Colour Constancy Techniques for Re-Recognition of Pedestrians from Multiple Surveillance Cameras (2008)

Colombo, Alberto, Orwell, James, Velastin, Sergio

This paper presents work towards a system for tracking the movements of a pedestrian as they move between the multiple sensors comprising a surveillance system. The colour appearance of the...
