Notizen: Abstract An algorithm to implement the Hough transform for the detection of a straight line on a pyramidal architecture is presented. The algorithm consists of two phases. The first phase, called block-projection, takes constant time. The second phase, called block-combination, is repeated logn times and takes a total ofO(n 1/2) time for the detection of all straight lines having a given slope on an n×n image; if there arep different slopes to be detected, then the total time becomesO(pn 1/2).
