Class implementing the AKAZE keypoint detector and descriptor extractor, described in 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.
