Web[H,theta,rho] = hough(BW) computes the Standard Hough Transform (SHT) of the binary image BW. The hough function is designed to detect lines. The function uses the parametric representation of a line: rho = x*cos(theta) + y*sin(theta).The function returns rho, the distance from the origin to the line along a vector perpendicular to the line, and … WebThe Hough Space is a 2D plane that has a horizontal axis representing the slope and the vertical axis representing the intercept of a line on the edge image. A line on an edge image is represented in the form of y = ax + b (Hough, 1962). One line on the edge image produces a point on the Hough Space since a line is characterized by its slope a ...
