Application of the Projected Hough Transform in Picture Processing.
Ulrich Eckhardt, Gerd Maderlechner · Pattern Recognition · 1988
P.V.C. Hough (1962) observed that in binary pictures lines correspond to maxima of the Radon transform. For this reason the Radon (or Hough) transform is frequently used in picture processing applications. Since the amount of data to be processed in performing this transformation can become very large, numerous approaches were proposed in the literature for data reduction by means of projection. In the present paper conditions are given for a generalized version of the Radon transform to yield useful results.
