Abstract
We are interested in designing a reusable and robust activity monitoring platform. We propose three good properties that an activity monitoring platform should have to enable its reusability for different applications and to insure performance quality: (1) modularity and flexibility of the architecture, (2) separation between the algorithms and the a priori knowledge they use, and (3) automatic evaluation of algorithm results. We then propose a development methodology to fulfill the last two properties. The methodology consists in the interaction between end-users and developers during the whole development of a specific monitoring system. To validate our approach, we present a platform used to generate activity monitoring systems dedicated to specific applications, we also describe in details the technical validation and the end-user assessment of an automatic metro monitoring system built with the platform and briefly the validation results for bank agency monitoring and building access control.
Highlights
The task of developing algorithms able to recognize human activities in video sequences has been an active field of research for the last ten years

Summary
The task of developing algorithms able to recognize human activities in video sequences has been an active field of research for the last ten years. We have built with VSIP three AMSs which have been validated by end-users: an activity monitoring system in metro stations, a bank agency monitoring system, and a lock chamber access control system for buildings security These applications present some characteristics which make them interesting for research purposes: the observed scenes vary from large open spaces (like metro halls) to small and closed spaces (corridors and lock chambers); cameras can have both nonoverlapping (like in metro stations and lock chambers systems) and overlapping fields of view (metro stations and bank agencies); humans can interact with the equipment (like ticket vending machines or access control barriers, bank safes and lock chambers doors) either in simple ways (open/close) or in more complex ones
