How Hough transform is used for edge detection?
Hough transform is an algorithm used to detect straight lines in images. It usually takes the output of an edge detection algorithm as an input (in our case, we use Canny for that). To find lines in an image, the algorithm maps the edge points in an image onto the polar coordinate system.What is the difference between Hough and Canny Edge Detection?
cvCanny is used to detect Edges, as well as increase contrast and remove image noise. HoughLines which uses the Hough Transform is used to determine whether those edges are lines or not. Hough Transform requires edges to be detected well in order to be efficient and provide meaning results.What is Hough transform used to detect?
The Hough transform (HT) [Hough62] is a technique that locates shapes in images. In particular, it has been used to extract lines, circles and ellipses (or conic sections). In the case of lines, its mathematical definition is equivalent to the Radon transform [Deans81].- Hough transform can detect lines, circles and other structures if their parametric equation is known. It can give robust detection under noise and partial occlusion • It can give robust detection under noise and partial occlusion. Borders between the regions are • Borders between the regions are straight lines.
