Detection of Straight Lines Using Rule Directed Pixel Comparison (RDPC) Method

摘要

A simple and efficient algorithm, based on Rule Directed Pixel Comparison, RDPC method, is proposed for detecting straight line segments in an edge image, based on certain specific rules, scanning column wise and labelling done in accordance with the application of rules. Four rules are formulated to detect the edge pixels which are part of straight lines with each straight line having two threshold values, minimum line length and minimum line level length. A comparison of the resultant image is made with Standard Hough Transform and other advanced algorithms.
