Expand description

Class implementing DAISY descriptor, described in Tola10

Parameters

  • 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.
