The authors discuss the need to provide a realistic model of a generic noise probability density function (PDF), in order to optimize the signal detection in non-Gaussian environments. The target is to obtain a model depending on a few parameters (that are quick and easy to estimate), and is so general that it is able to describe many kinds of...

This work presents a location determination technique which is based on wireless local area networks (WLANs), in particular the IEEE 802.11b standard, in conjunction with GPS (Global positioning system). Since each of the positioning devices has its shortcomings, this paper proposes to use the data obtained from the GPS system together with the...

In this paper, an algorithm for tracking multiple rigid and non-rigid objects in conditions of occlusions is presented. The proposed method is based on a scalable and adaptive model based on joint information of color and shape. Through a GHT (Generalized Hough Transform) based voting method the center of mass of each object can be determined...

The objective of the PASSWORDS Project is to design and develop a prototype of an intelligent video image analysis system for video surveillance and security applications, based on concrete needs expressed by potential users. The goal of the system developed within PASSWORDS is to detect certain dangerous situations in some scenes (e.g....
