Back story
Long before VisionTools existed, our company founder Dr. Hermann Tropf had been scientifically involved in the field. As head of the machine vision group at the Fraunhofer Institute for Information and Data Processing in Karlsruhe (today IOSB), he was one of the pioneers of industrial image processing. Theoretical work was awarded prizes (IEEE Computer Society Pattern Recognition Award 1980, German Association for Pattern Recognition extra award 1987), pioneering practical applications successfully ran over the long term at VW, Ford and Siemens. https://hermanntropf.de/media/Details_Gruppe_Fraunhofer.pdf (in German)
A fundamental work on multidimensional range search in mass data found its way into diverse technical applications and into today commercial big data systems. https://hermanntropf.de/media/Z-Curve_LITMAX_BIGMIN_History_and_Applications_en.pdf
