Detailed Description

Abstract base class for CUDA asynchronous 2D image feature detectors and descriptor extractors.

Constructor & Destructor Documentation

virtual cv::cuda::Feature2DAsync::~Feature2DAsync ( )

virtual

virtual void cv::cuda::Feature2DAsync::computeAsync	(	InputArray	image,
		OutputArray	keypoints,
		OutputArray	descriptors,
		Stream &	stream = `Stream::Null()`
	)

virtual

Computes the descriptors for a set of keypoints detected in an image.

Parameters

image	Image.
keypoints	Input collection of keypoints.
descriptors	Computed descriptors. Row j is the descriptor for j-th keypoint.
stream	CUDA stream.

virtual void cv::cuda::Feature2DAsync::convert	(	InputArray	gpu_keypoints,
		std::vector< KeyPoint > &	keypoints
	)

pure virtual

Converts keypoints array from internal representation to standard vector.

virtual void cv::cuda::Feature2DAsync::detectAndComputeAsync	(	InputArray	image,
		InputArray	mask,
		OutputArray	keypoints,
		OutputArray	descriptors,
		bool	useProvidedKeypoints = `false`,
		Stream &	stream = `Stream::Null()`
	)

virtual

Detects keypoints and computes the descriptors.

virtual void cv::cuda::Feature2DAsync::detectAsync	(	InputArray	image,
		OutputArray	keypoints,
		InputArray	mask = `noArray()`,
		Stream &	stream = `Stream::Null()`
	)

virtual

Detects keypoints in an image.

Parameters

image	Image.
keypoints	The detected keypoints.
mask	Mask specifying where to look for keypoints (optional). It must be a 8-bit integer matrix with non-zero values in the region of interest.
stream	CUDA stream.
