This paper introduces a system for video object extraction useful for general applications
where foreground objects move within a slow changing background. Surveillance of indoor …

Knowing the background image of a video scene simplifies the general video-object
segmentation problem and therefore it is required by several automatic segmentation …

The Real time locating system (RTLS) determines and tracks the location of assets and
people. This paper presents a novel application to estimate the position and velocity of …

This paper presents a new technique for simultaneous traffic monitoring and law
enforcement using a roadside rig head based on two line-scan cameras. As the vehicle …

Tracking objects that take part in sportive events is a challenging task because the objects
move fast and occlusions occur frequently. When the tracked area is large, the use of more …

This text represents what is visible of the Ph. D. work I carried out in the last four years at the
Signal Processing Institute. During this time I received advice, help and support from many …

The Connected Component Tree (CCT)-based operators play a central role in the
development of new algorithms related to image processing applications such as pattern …

An image sequence stabilization system that removes translational jitter while preserving
intentional camera pan is presented. The video sequence is processed to acquire global …

This paper proposes a new method for the detection of moving cast shadows in natural
video sequences. The variations of illumination generate in a shadow area are modelized …

This thesis presents a collection of photogrammetry techniques aimed at the analysis of
short-lived events. The small time scale on which these phenomena happen makes them …
