2016-04-07 05:46:07 -0600 | asked a question | Canny dynamic threshold [update] Thanks for one of the comments that remind me of the possibility that it doesn't find anything useful at all... I modified the threshold I used in creating edge map, and it started to work correctly! However, I am wondering if there is a more robust way to generate dynamic threshold for canny edge detection? below is the img I used
I have found a similar post here: http://answers.opencv.org/question/14... but I'm using version 3.0, anyone has the same problem? Here is my code... However, the returned value is always zero. Thanks in advance! |
