Abstract: The algorithm that extracts edge straight lines using parametric con trol on intensity images is proposed. This algorithm solves the difficult proble m of efficiently extracting straight lines in the domain of image understanding. Besides the basic orientation and position parameters, the properties of lines, such as contrast, width, and steepness, also can be achieved. The experiment sh ows that this algorithm is very effective and efficient, and can produce signifi cant information.
