Member Function Documentation

computeAsync()

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.

convert()

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

pure virtual

Converts keypoints array from internal representation to standard vector.

detectAndComputeAsync()

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.

detectAsync()

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.
