I want to get a set of all 8-connected paths that are produced by canny edge detection algorithm so I can analyze them independently. Is there a way to do it using OpenCV or any other C++ library without having to implement it myself?

I already have the edges detected, what I need is to find 8-connected paths on the detected edges.

  • This question is unclear. Are you looking for an implementation of the CANNY edge detection algorithm? Or a post-processing step to identify the paths? What have you done so far? – Ben Voigt Mar 18 '13 at 15:41
  • No, I already have the edges detected by CANNY, I want to separate them to analyze each edge independently, in other words, find 8-connected paths on the output of CANNY – ButterDog Mar 18 '13 at 15:44

    Does cvFindContours() help? – Roger Rowland Mar 18 '13 at 15:47

    That's exactly what I need. You should add it as an answer to close the question. Thanks – ButterDog Mar 18 '13 at 15:55
