 GEPARD has a long-term reputation for finding a solution to really challenging problems. This reputation has already raised a number of technically and scientifically highly interesting and innovative projects. But also 'standard' developments took benefit from the creative approach of the team. GEPARD has a long-term reputation for finding a solution to really challenging problems.

-CineSat is a powerful, high-performance, and feature-rich meteorological software suite for satellite image analysis, display, and processing. It features a real-time weather analysis and forecasting module based on satellite imagery, a high-performance and highly-configurable Automatic Product Extraction Server with a number of unique functions, and a strong and fast data display.+Operational software for multi-spectral Landsat image classification to identify and monitor forest damages based on methods previously developed for airborne infra-red images. 
  
-25 years ago, CineSat had started as an in-house research and development project, initiated by customer requests for a high-performance satellite image interpretation system. Designed to best possibly assist the forecaster's operational routine work. With start of Meteosat 2nd Generation in 2003, CineSat became a well appreciated standard software solution for real-time processing of meteorological data distributed via EUMETCast.+We started by computing a large set of scale- and rotation-invariant image features from each spectral channel of the Landsat Thematic Mapper. These more than 70 feature fields per image were then reduced to a handful of most significant features by principal component analysis. 
 +This selected feature set was used as input to cluster analysis and forest damage classification.
  
 +We implemented these methods on a parallel computing hardware to significantly speed up processing. This allowed to improve the classification by evaluating many more data sets.

 +<wrap red>Description:</wrap> 
 +Great echo on GEPARD´s 'Dream Factory' at the world's biggest industrial fair, 1989.  
 + 
 +The demonstrator was **built on a parallel computer with exceptional display and processing performance** and 
 +  * Could be configured for different production lines consisting of conveyor belts, work places, transport crane, handling robot, forklift, different size and weight of goods, etc 
 +  * Simulated the configured production line by discrete event simulation 
 +  * Solved the differential equations to simulate e.g. the behavior of goods on the transport crane (acceleration, swinging, ...) 
 +  * Accepted real-time user interaction via keyboard, joystick, and analog and digital interfaces 
 +  * Animated the production process with real-world images at 25 images per second 
 +  * Imported real-time images from a video camera and projected the live faces of spectators onto packed goods 
 +  * The user could also take control of the transport crane and move it with a joystick. The challenge was that the goods were not released from the crane before it stopped swinging. 
 + 
 +In the following year, we extended the demonstrator hawith industrial controls and a real handling robot: 
 + 
 +  * Visitors saw the real-world image animation of the simulated production process on screen and a small real robot sitting on the table next to the screen. 
 +  * Whenever the goods on a simulated conveyor belt reached the station of the simulated handling robot, the real robot picked up a goody from the table and handed it to a visitor.  
 +  * Halting or slowing down the real robot also stopped or slowed the simulated robot on the animation display, and the goods started to pile up on the conveyor belts, until the whole production came to a halt. 
 + 
 +This setup demonstrated the seamless integration of simulation, animation and reality, and was the start of several hardware-in-the-loop simulation projects for some well-known companies like Volkswagen, VOEST, ...
