SUP

Figure 2. Components of the Scene Understanding Platform (SUP).

SUP is a Scene Understanding Software Platform written in C and C++ (see Figure 2 ). SUP is the continuation of the VSIP platform. SUP is splitting the workflow of a video processing into several modules, such as acquisition, segmentation, etc., until scenario recognition. Each module has a precise interface, and different plugins implementing these interfaces can be used for each step of the video processing. This generic architecture is designed to facilitate:

1. integration of new algorithms in SUP;

2. sharing of the algorithms among the team.

Currently, 15 plugins are available, covering the whole processing chain. Several plugins are using the Genius platform, an industrial platform based on VSIP and exploited by Keeneo, the Orion/Pulsar spin off created in July 2005.

Goals of SUP are twofolds:

1. From a video understanding point of view, to allow the researchers of the Pulsar team can share the implementations of their researches through this platform.

2. From a software engineering point of view, to integrate the results of the dynamic management of the applications when applied to video surveillance.
