THE HOUGH TRANSFORM AS A TOOL FOR IMAGE ANALYSIS
Josep Lladós · 2003
The Hough transform is a widespread technique in image analysis. Its main idea is to transform the image to a parameter space where clusters or particular configurations identify instances of a shape under detection. In this chapter we overview some meaningful Hough-based techniques for shape detection, either parametrized or generalized shapes. We also analyze some approaches based on the straight line Hough transform able to detect particular structural properties in images. Some of the ideas of these approaches will be used in the following chapter to solve one of the goals of the present work.
