Conductivity functions speeded-up by using raw pointer access
Raw pointer access in compute_k_percentile
Raw pointer access done in nld_step_scalar
More optimal Do_Subpixel_Refinement
Use create in Allocate_Memory_Evolution, it is faster than calling
cv::Mat
Speeded-up Compute_Determinant_Hessian_Response
Speeded-up Find_Scale_Space_Extrema
Minor modifications
Cleaner prime detection function
Some minor style modifications
Use of libAKAZE namespace to avoid conflicts with AKAZE in OpenCV 3.0
akaze_compare and akaze_match now accept homography.txt as an optional
parameter. If the homography is not provided, it will be automatically
estimated using RANSAC
