Struct opencv::xfeatures2d::DAISY
source · pub struct DAISY { /* private fields */ }
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.

unsafe fn modify_inplace<Res>( &mut self, f: impl FnOnce(&Mat, &mut Mat) -> Res ) -> Res
Helper function to call OpenCV functions that allow in-place modification of a
Mat
or another similar object. By passing
a mutable reference to the Mat
to this function your closure will get called with the read reference and a write references
to the same Mat
. This is of course unsafe as it breaks the Rust aliasing rules, but it might be useful for some performance
sensitive operations. One example of an OpenCV function that allows such in-place modification is imgproc::threshold
. Read more
