WebDec 31, 2024 · The Hough transform is all about doing what we just learned: converting points in the xy space to lines in the mc space. You take an edge detected image, and for every point that is not black, you draw lines in the mc place. Obviously, some lines will intersect. These intersection marks are the parameters of the line.
