The detection of parallel straight lines with the application of the Hough transform
J. Krahe, P. Pousset · 2003
Problems posed by the application of the Hough transform to a small-scale image are discussed. It is shown that the discretization of image space makes the distribution of parameters in Hough space nonhomogeneous and nonequiprobable. A method of correction is presented in the case of the detection of parallel straight lines on a square scan window.>
