Note: This distance computation … Web8 de jan. de 2013 · If it is going above the origin, instead of taking an angle greater than 180, the 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. Now let's see how the Hough Transform works for lines. Any line can be represented in these two terms, \((\rho, \theta)\).
