What is the formula for Hough transform?
[ 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) .How do you use Hough transform?
Algorithm
1Determine the range of ? and ?. 2Create a 2D array called the accumulator with the dimensions (num rhos, num thetas) to represent the Hough Space and set all its values to zero.3Use the original Image to do edge detection (ED). 4Check each pixel on the edge picture to see if it is an edge pixel.What is the application of Hough transform in image processing?
The Hough transform (HT) can be used to detect lines circles or • The Hough transform (HT) can be used to detect lines, circles or other parametric curves. It was introduced in 1962 (Hough 1962) and first used to find lines in images a decade later (Duda 1972). The goal is to find the location of lines in images.- In image processing, line detection is an algorithm that takes a collection of n edge points and finds all the lines on which these edge points lie. The most popular line detectors are the Hough transform and convolution-based techniques.
