Edge pixels mapping to the same theta and r are assumed to define a line in the image. To compute the frequency … WebDefinition. The Hough transform (HT) is a coordinate transformation introduced by Hough (Hough 1962 ). It is useful in computer vision as a method for retrieving shapes within digital images. It was first conceived for lines, circumferences, and simple polygons (Duda and Hart 1972) and later generalized to arbitrary shapes (Ballard 1981 ). thermoplaste skizze
