class |
BEBLID
Class implementing BEBLID (Boosted Efficient Binary Local Image Descriptor),
described in CITE: Suarez2020BEBLID .
|
class |
BoostDesc
Class implementing BoostDesc (Learning Image Descriptors with Boosting), described in

|
class |
BriefDescriptorExtractor
Class for computing BRIEF descriptors described in CITE: calon2010 .
|
class |
DAISY
Class implementing DAISY descriptor, described in CITE: Tola10
radius radius of the descriptor at the initial scale
q_radius amount of radial range division quantity
q_theta amount of angular range division quantity
q_hist amount of gradient orientations range division quantity
norm choose descriptors normalization type, where
DAISY::NRM_NONE will not do any normalization (default),
DAISY::NRM_PARTIAL mean that histograms are normalized independently for L2 norm equal to 1.0,
DAISY::NRM_FULL mean that descriptors are normalized for L2 norm equal to 1.0,
DAISY::NRM_SIFT mean that descriptors are normalized for L2 norm equal to 1.0 but no individual one is bigger than 0.154 as in SIFT
H optional 3x3 homography matrix used to warp the grid of daisy but sampling keypoints remains unwarped on image
interpolation switch to disable interpolation for speed improvement at minor quality loss
use_orientation sample patterns using keypoints orientation, disabled by default.
