Does anyone know the concept of using HoughLines in OpenCV for line detection? I am just starting learn opencv with its tutorials but still confused about how to use houghlines

Well, what part are you confused about? That tutorial is pretty straight forward, but we can help you if we know what it is that you don't understand.

This i confused :

  • In the Cartesian coordinate system: Parameters: (m,b).

  • In the Polar coordinate system: Parameters: (r,\theta)

  • The Standard Hough Transform

  • The Probabilistic Hough Line Transform

There are 2 methods of doing the detection of the lines: standard and probabilistic. Hough is based on polar coordinates, so you need to convert them for displaying the lines in Cartesian coordinates (used by line function)

may i know what is the different between method of detect the line?
