抄録

In this paper, we proposed a new algorithm RVHT (Randomized Voting HT). RVHT is an improved PHT, in which edge points are deleted from the edge image according to the sequential line detection process of PHT.<br>The relations between RVHT and RHT algorithms were discussed both experimentally and theoretically. It was clarified theoretically that RVHT becomes strictly equivalent to RHT when the sequence of the combinations of two edge points is selected in a specified order, and experimentally that the proposed RVHT can detect shorter edge lines than RHT by using real microscopic images. As a result, several practical knowledges were presented for the practical use of Hough transform.
