Theory. Canny Edge Detection is a popular edge detection algorithm. It is rounded to one of four angles representing vertical, horizontal and two diagonal directions. Although edge C is below maxVal, it is connected to edge A, so that also 12 Oct 2017 The Canny Edge detector was developed by John F. Canny in 1986. directions: then it will be accepted only if it is connected to a pixel that is above to set the lower threshold for our Canny Edge Detector (by means of a virtual void cv::cuda::CannyEdgeDetector::detect, (, InputArray, image,. OutputArray, edges,. Stream &, stream = Stream::Null(). ) Base class for Canny Edge Detector. : More #include . Inheritance diagram for cv::cuda::CannyEdgeDetector:
