The work presented in this paper is intended to test crucial system services against stack overflow vulnerabilities. The focus of the test is the user-accessible variables, that i...
Programming on the Web enlights some classical problems encountered on large distributed applications with a particular emphasis on dynamic changes. In that context, we are intere...
We present an integrated pixel segmentation and region tracking algorithm, designed for indoor environments. Visual monitoring systems often use frame differencing techniques to i...
This paper describes the architecture of a visual surveillance system that combines real time computer vision algorithms with logic programming to represent and recognize activiti...
A powerful strategy in intrusion detection is the separation of surveillance mechanisms from a site’s policy for processing observed events. The Bro intrusion detection system h...
