Since a market analysis showed no product for real-time grabbing of selectable video image regions on the fly, a cooperation with the Institut fuer Messtechnik (Prof. V. Graefe) was started, leading to the first series of "Bildvorv erarbeitungssystemen" (BVVx, image sequence preprocessing systems). The first one was an 8-bit system with a special video-bus (1979 - 83); in 84, the 16-bit BVV_2 followed, which gradually was improved with 32-bit processors [DiG 88]. These systems, in combination with the 4-D approach (see below), set some standards in performance level as compared to the massively parallel systems in use elsewhere at that time.

These first generation systems have been in use till the early 90ies when transputers took over, augmented by the type of video-bus successfully demonstrated. Up to 60 transputers have been active in the test vehicle VaMP in the Paris demo at the end of the EUREKA-Prometheus project in October 1994. When the follow-on transputer generation T-9000 failed its way to market, PowerPC in connection with the old transputer system formed a transition phase (1995 - 97) from the second to the third generation vision systems. These have been developed since 1997 on commercial-off-the-shelf general purpose PC hardware (Pentium-generation) and Windows NT as operating system (OS). The current (2000) vision system consists of 4 dual Pentium II / III PCs interconnected by a high performance Scalable Coherent Interface (SCI) network as communication backbone.
