Detailed Description

Class implementing the AKAZE keypoint detector and descriptor extractor, described in [ANB13].

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.; AKAZE implements T-API. When image is passed as UMat some parts of the algorithm will use OpenCL.; [ANB13] Fast Explicit Diffusion for Accelerated Features in Nonlinear Scale Spaces. Pablo F. Alcantarilla, Jesús Nuevo and Adrien Bartoli. In British Machine Vision Conference (BMVC), Bristol, UK, September 2013.
