AKAZE (Accelerated-KAZE) is an algorithm that speeds up the KAZE keypoint detector, which builds its scale space with nonlinear diffusion filtering. It accelerates scale space construction with the Fast Explicit Diffusion (FED) scheme and lowers matching cost by using the binary descriptor M-LDB. It is included in OpenCV's features2d module as cv::AKAZE, and like ORB it can be used for keypoint matching and planar tracking.
