Detailed Description

Class implementing the KAZE keypoint detector and descriptor extractor, described in [6] .

AKAZE descriptor can only be used with KAZE or AKAZE keypoints .. [ABD12] KAZE Features. Pablo F. Alcantarilla, Adrien Bartoli and Andrew J. Davison. In European Conference on Computer Vision (ECCV), Fiorenze, Italy, October 2012.

§ create()

static Ptr<KAZE> cv::KAZE::create ( bool  extended = false,
bool  upright = false,
float  threshold = 0.001f,
int  nOctaves = 4,
int  nOctaveLayers = 4,
int  diffusivity = KAZE::DIFF_PM_G2 

The KAZE constructor.

extendedSet to enable extraction of extended (128-byte) descriptor.
uprightSet to enable use of upright descriptors (non rotation-invariant).
thresholdDetector response threshold to accept point
nOctavesMaximum octave evolution of the image
nOctaveLayersDefault number of sublevels per scale level
diffusivityDiffusivity type. DIFF_PM_G1, DIFF_PM_G2, DIFF_WEICKERT or DIFF_CHARBONNIER
