| 2014-03-07 14:35:32 -0600 | asked a question | How is contour data ordered? I want to find straight lines within a contour without the need for Hough. I want to simply walk along a contour and extract the straight lines when doing so. My question is how the contour data is ordered after finding contours? Are they ordered in a list with connected parts one after another? Or will I need to sort the data that way myself first. |

| 2013-11-01 12:31:30 -0600 | asked a question | Does the canny method apply non-maximum suppression? Looking at the OpenCV description of Canny edge detection non-maximum suppression is discussed as one of the steps. However, so is Gaussian blurring, and according to this question/answer blurring is not automatically applied during the canny method. Yet, the tutorial Canny edge detection code (from the first link) only specifically adds the blurring but not the non-maximum suppression. Is the non-maximum suppression automatically included in the canny method? If not, is there an OpenCV function to preform the non-maximum suppression? Thank you much! |
