Title: | The Hough transformation of rectangle | Authors: | Ralević, Nebojša Dražić S. Obradović, Ratko |
Issue Date: | 1-Dec-2008 | Journal: | SISY 2008 - 6th International Symposium on Intelligent Systems and Informatics | Abstract: | Hough transformation for finding straight line segments is well known in digital image processing. In this paper we have used hough, houghline and houghpeaks functions for creating a new 4 - dimensional parameter space named h_space for extracting rectangles in digital image. These parameters are coordinates of the center of a rectangle (intersection of diagonals), angle that the shorter edge makes with x-axis and length of the longer edge. In our opinion this result might be useful for the shape descriptors associated with rectangles because the parameters of h_space are suitable for calculating descriptors of a rectangle (like area and perimeter) and they give a good idea about the position of a rectangle. ©2008 IEEE. | URI: | https://open.uns.ac.rs/handle/123456789/13378 | DOI: | 10.1109/SISY.2008.4664906 |
