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

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

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.

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

Converts keypoints array from internal representation to standard vector.

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

Detects keypoints and computes the descriptors.

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

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.
