A good approach for detecting lines in an image?


A good approach for detecting lines in an image? - Stack Overflow

I've written some code that uses OpenCV libraries to detect white lines painted on grass. I need someone's opinion on the approach I used.

Line Detection

Note that the Hough transform can be used to detect lines; however, in that case, the output is a parametric description of the lines in an image. How It Works.

How to identify clear straight lines using computer vision? - Reddit

From fundamentals, use hough transform. You need to pre-process the images to get an edge map (canny is the best, but sobel is also ok).

Line detection - Wikipedia

In image processing, line detection is an algorithm that takes a collection of n edge points and finds all the lines on which these edge points lie.
