Paper Abstract

In this paper, we propose a new Hough transform algorithm, Least Median of Squares (LMedS) Hough transform, which uses the measure of the least median of squares as the basis to estimate lines. This means that LMedS Hough transform can provide a new measure for finding lines as an alternative to the majority standard of the ordinary Hough transform and, therefore, that LMedS Hough transform can detect lines in the same way as LMedS line fitting procedure. In addition to this, because this algorithm is constructed on the Hough transform paradigm, the basic properties of Hough transform such as noise robustness, multi-line detection and global line detection are inherited in LMedS Hough transform algorithm.
