Accurate and efficient curve detection in images: the importance sampling Hough transform

  journal={Pattern Recognition},
The Hough transform is a well known technique for detecting parametric curves in images. We place a particular group of Hough transforms, the probabilistic Hough transforms, in the framework of importance sampling. This framework suggests a way in which probabilistic Hough transforms can be improved: by specifying a target distribution and weighting the sampled parameters accordingly to make identi1cation of curves easier. We investigate the use of clustering techniques to simultaneously… CONTINUE READING
