The Improved Approach of Straight Line Segments Detection Based on Hough Transform
Ailian Jiang · Microcomputer Information · 2010
The Hough Transform is an efficient algorithm in straight line segments detection field, however, there are deficiencies in the classical Hough transform, such as the great deal of operation, the wrong connection of the break-line and etc. By analyzing the principle of the Hough transform, we improve a method to make a threshold to avoid inefficient pixels, and another threshold to segment straight lines. It is proved that, compared with classical Hough transform, this method reduce the complexity of operation, and avoid the lost of short straight lines.
