Required Methods

Provided Methods

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()

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()

Detects keypoints and computes the descriptors.

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

Converts keypoints array from internal representation to standard vector.
