Thomas Buchanan [bju: kænen] (born June 22, 1942 in New York City ) is an American-German computer scientist . He is a professor for graphic data processing.

Life

Thomas (Tom) Buchanan was born in the USA in 1942. He attended the St. Thomas Choir School in New York City - an institution that is comparable to the Thomas School in Leipzig . After graduating from school, he began studying at Deleware University . Then followed a three-year service in the US Army , during which he was mainly stationed in Stuttgart . After his military service he returned to the USA. Here he worked at the DuPont research center as a chemical engineer in a department for inorganic synthesis.

In 1967 he went back to the Federal Republic of Germany to attend the University of Tuebingen a degree in mathematics take. After graduating as a qualified mathematician , he worked on a dissertation and received his doctorate in the field of mathematics in 1979 at the University of Erlangen-Nuremberg (reviewer / reporter: Karl Strambach , Peter Plaumann ).

After completing his doctorate, he moved to Darmstadt and worked in the private sector for various software companies. From 1981 to 1989 he worked in the former television systems division of Robert Bosch GmbH , where he developed special software for industrial image recognition systems. He then worked for the English software house Logica in a German branch.

In 1994 Thomas Buchanan was appointed professor of computer science specializing in graphic data processing at the then Merseburg University of Applied Sciences , which later developed into the Merseburg University of Applied Sciences . In 1995 the family moved to Merseburg near Halle (Saale) in Saxony-Anhalt .

His academic teaching related to the fields of logic , algebra , geometry , computer graphics , image processing , software engineering , and artificial intelligence (AI).

The research of Buchanan included as a priority area, the "computer vision", ie the computer used in conjunction with video cameras for the development of an automated system for the technical vision with various applications such. B. in mobile robots. Buchanan's main interest here was the generation of spatial models (3D) from two-dimensional images ( photogrammetry ), in particular with the use of algebraic geometry in the algorithms for image evaluation. In particular, he dealt with the geometry of straight lines in three-dimensional space as well as algorithms for the evaluation of images for scenes that contain straight lines.

Thomas Buchanan is married to Irene Buchanan , who holds a doctorate in biology and is a freelance painter, graphic artist and draftsman . The couple have a daughter and a son. Buchanan is a passionate organ player, and he particularly plays the church and cathedral organs in Merseburg.
