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
imageImage.
keypointsInput collection of keypoints.
descriptorsComputed descriptors. Row j is the descriptor for j-th keypoint.
streamCUDA 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
imageImage.
keypointsThe detected keypoints.
maskMask specifying where to look for keypoints (optional). It must be a 8-bit integer matrix with non-zero values in the region of interest.
streamCUDA stream.
