Objectives:
Given one
pan-tilt-zoom camera the long-term objective consists in automating the monitoring
of changes in a scenario. An example application is inventory check in a museum
room, where the pan-tilt-zoom camera at the end of the day browses the scenario
to confirm all museum pieces are at their desired locations.
Pan-tilt-zoom cameras
provide very high resolution at widely separated points of interest. Mosaicing at the highest resolution requires large amounts
of memory. Minimizing the memory requirements, without exaggerating the
computational requirements, is a central objective of this thesis.
This project is based
in the research and development of two fundamental components:
(i)
pan-tilt-zoom camera geometric modeling and calibrating
(ii) integrating
changes in the background model of the scenario
(iii) detecting
modifications of the scenario

Observations:
Previous works
conducted at ISR/IST provide good starting points for the thesis. In particular
a number of software prototypes already exist for target detection, tracking
and camera scheduling.
