computer vision - Understanding rho and theta in hough

WebJan 8, 2011 · So if line is passing below the origin, it will have a positive rho and angle less than 180. If it is going above the origin, instead of taking angle greater than 180, angle is taken less than 180, and rho is taken negative. Any vertical line will have 0 degree and horizontal lines will have 90 degree. WebHoughLines returns lines in rho, theta form (Hesse normal form), and the theta returned is between 0 and 180 degrees, and lines around 180 and 0 degrees are similar (they are both close to horizontal lines), so we need some way to get this periodicity in kmeans. personalized books for new baby gift https://zemakeupartistry.com
