History
It was initially invented for machine analysis of bubble chamber photographs (Hough, 1959).
The Hough transform was patented as U.S. Patent 3,069,654 in 1962 and assigned to the U.S. Atomic Energy Commission with the name "Method and Means for Recognizing Complex Patterns". This patent uses a slope-intercept parametrization for straight lines, which awkwardly leads to an unbounded transform space since the slope can go to infinity.
The rho-theta parametrization universally used today was first described in
- Duda, R. O. and P. E. Hart, "Use of the Hough Transformation to Detect Lines and Curves in Pictures," Comm. ACM, Vol. 15, pp. 11–15 (January, 1972),
although it was already standard for the Radon transform since at least the 1930s.
O'Gorman and Clowes' variation is described in
- Frank O'Gorman, MB Clowes: Finding Picture Edges Through Collinearity of Feature Points. IEEE Trans. Computers 25(4): 449-456 (1976)
The story of how the modern form of the Hough transform was invented is given in
- Hart, P. E., "How the Hough Transform was Invented", IEEE Signal Processing Magazine, Vol 26, Issue 6, pp 18 - 22 (November, 2009) .

Famous quotes containing the word history:
“It’s nice to be a part of history but people should get it right. I may not be perfect, but I’m bloody close.”
—John Lydon (formerly Johnny Rotten)
“Three million of such stones would be needed before the work was done. Three million stones of an average weight of 5,000 pounds, every stone cut precisely to fit into its destined place in the great pyramid. From the quarries they pulled the stones across the desert to the banks of the Nile. Never in the history of the world had so great a task been performed. Their faith gave them strength, and their joy gave them song.”
—William Faulkner (1897–1962)
“American time has stretched around the world. It has become the dominant tempo of modern history, especially of the history of Europe.”
—Harold Rosenberg (1906–1978)
