The straight lines can be detected by means of Hough transform in which a different straight line is mapped by a different point. In the detection of two or more lines involved within a digital image, their corresponding points in the Hough transform space must be identified correctly on the basis of the above principle. In the present study, the labeling technique in the digital image processing is used in order to identify them in the Hough transform space. Furthermore, the labeling technique is also used in a stage of the inverse Hough transform in order to determine the restricted region of the finite straight lines to be detected.
