What are we going to do? The scene needs a framework Easier way to implement application Interoperability New possibilities (more on this later) The framework will extract information from the world, and will give the opportunity to select what is relevant The Framework Users or Companies

Input Devices (Camera) Input Analysis INCAPS Picture Processing Output Devices (Projector) Internal world representation

DB Modules The world as a source.. We have to represent the world internally to understand it better Single components are not enough All the input devices are used to sample the world on different aspects (a lot of information out there!) REALTIME! The Project Planning

First year: Research and tests of algorithms on multiple input devices, setup and tuning. Second year: Have an efficient internal world representation. Third year: Addition of multiple input/output devices, creation of APIs Reality 2 Digital Reality 2 Digital 3D Information Extraction We have an internal world-map, we can

specify rules (I.e. pedestrians) Companies/Users can decide what is important (tumors, broken bones, road, traffic signs,components) Possibility to apply further algorithms to subsets of world-data Depending on the application, we can recognize and label objects, matching them with databases and ad-hoc algorithms Digital 2 Reality The extracted information is displayed to the user in the most useful way,

depending on the application. Digital 2 Reality: Examples Night Vision Pedestrian detection Equipment Costs Estimation A very powerful computer, a car and .. Input Devices:

Stereo Camera Radars IR Night-viewer Database System Wireless Communication GPS Output Devices :
