Mutable methods for crate::cudafeatures2d::CUDA_Feature2DAsync

Required Methods§

source

fn as_raw_mut_CUDA_Feature2DAsync(&mut self) -> *mut c_void

Provided Methods§

source

fn detect_async( &mut self, image: &impl ToInputArray, keypoints: &mut impl ToOutputArray, mask: &impl ToInputArray, stream: &mut impl StreamTrait, ) -> Result<()>

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.
§C++ default parameters
  • mask: noArray()
  • stream: Stream::Null()
source

fn detect_async_def( &mut self, image: &impl ToInputArray, keypoints: &mut impl ToOutputArray, ) -> Result<()>

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.
§Note

This alternative version of CUDA_Feature2DAsyncTrait::detect_async function uses the following default values for its arguments:

  • mask: noArray()
  • stream: Stream::Null()
source

fn compute_async( &mut self, image: &impl ToInputArray, keypoints: &mut impl ToOutputArray, descriptors: &mut impl ToOutputArray, stream: &mut impl StreamTrait, ) -> Result<()>

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.
§C++ default parameters
  • stream: Stream::Null()
source

fn compute_async_def( &mut self, image: &impl ToInputArray, keypoints: &mut impl ToOutputArray, descriptors: &mut impl ToOutputArray, ) -> Result<()>

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.
§Note

This alternative version of CUDA_Feature2DAsyncTrait::compute_async function uses the following default values for its arguments:

  • stream: Stream::Null()
source

fn detect_and_compute_async( &mut self, image: &impl ToInputArray, mask: &impl ToInputArray, keypoints: &mut impl ToOutputArray, descriptors: &mut impl ToOutputArray, use_provided_keypoints: bool, stream: &mut impl StreamTrait, ) -> Result<()>

Detects keypoints and computes the descriptors.

§C++ default parameters
  • use_provided_keypoints: false
  • stream: Stream::Null()
source

fn detect_and_compute_async_def( &mut self, image: &impl ToInputArray, mask: &impl ToInputArray, keypoints: &mut impl ToOutputArray, descriptors: &mut impl ToOutputArray, ) -> Result<()>

Detects keypoints and computes the descriptors.

§Note

This alternative version of CUDA_Feature2DAsyncTrait::detect_and_compute_async function uses the following default values for its arguments:

  • use_provided_keypoints: false
  • stream: Stream::Null()
source

fn convert( &mut self, gpu_keypoints: &impl ToInputArray, keypoints: &mut Vector<KeyPoint>, ) -> Result<()>

Converts keypoints array from internal representation to standard vector.
