WebThe Standard Hough Transform (SHT) uses the parametric representation of a line: rho = x*cos (theta) + y*sin (theta) The origin of the coordinate system is assumed to be at the center of the upper-left corner pixel. The variable rho is the perpendicular distance from the origin to the line. WebThe Hough transform is commonly used for detecting linear features within an image. A line is mapped to a peak within parameter space corresponding to the parameters of the line. By analysing the shape of the peak, or peak locus, within parameter space, it is possible to also use the line Hough transform to detect or analyse arbitrary (non …
