Member Function Documentation

virtual void cv::cuda::CannyEdgeDetector::detect	(	InputArray	image,
		OutputArray	edges,
		Stream &	stream = `Stream::Null()`
	)

pure virtual

Finds edges in an image using the [24] algorithm.

Parameters

image	Single-channel 8-bit input image.
edges	Output edge map. It has the same size and type as image.
stream	Stream for the asynchronous version.

virtual void cv::cuda::CannyEdgeDetector::detect	(	InputArray	dx,
		InputArray	dy,
		OutputArray	edges,
		Stream &	stream = `Stream::Null()`
	)

pure virtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters

dx	First derivative of image in the vertical direction. Support only CV_32S type.
dy	First derivative of image in the horizontal direction. Support only CV_32S type.
edges	Output edge map. It has the same size and type as image.
stream	Stream for the asynchronous version.
