The tutorial url link is as follow: http://docs.opencv.org/doc/tutorials/imgproc/imgtrans/hough_lines/hough_lines.html
i'm new as a learner of opencv line detection. When i'm reading the 'Theory' part of the tutorial, i find some of the easy formulas cannot be proven (because i took the meaning of the formulas wrong).
Then i 'wiki'ed 'Hough Transform', get the main idea of the theory. Then i realized that the 'Theory' part may be lack of some information about parameter descriptions, like what is '(m, b)' and '(r, theta)'.
I'm thinking if a update of this tutorial is needed. Or maybe it's just my wrong understanding of something already known well for all, like 'Polar System', that made me confused.
