public class AKAZE
extends Feature2D

\brief Class implementing the AKAZE keypoint detector and descriptor extractor, described in \cite ANB13.

\details AKAZE descriptors can only be used with KAZE or AKAZE keypoints. This class is thread-safe.

\note When you need descriptors use Feature2D::detectAndCompute, which provides better performance. When using Feature2D::detect followed by Feature2D::compute scale space pyramid is computed twice.

\note AKAZE implements T-API. When image is passed as UMat some parts of the algorithm will use OpenCL.

\brief The AKAZE constructor

Parameters:

descriptor_type - Type of the extracted descriptor: DESCRIPTOR_KAZE, DESCRIPTOR_KAZE_UPRIGHT, DESCRIPTOR_MLDB or DESCRIPTOR_MLDB_UPRIGHT.
