WebMar 3, 2024 · If the first canny remove too much information and no lines, the second function will suck. If you do a "first pass", removing much of the information but leaving very apparent lines, then the Hough Line has little to do. But I discovered that by tweaking the parameter of the Hough Line in the first time could achieve almost the same result.
