Struct opencv::xfeatures2d::DAISY

pub struct DAISY { /* private fields */ }

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.

fn write_with_name_def(&self, fs: &Ptr<FileStorage>) -> Result<()>

👎Deprecated:

Note

Deprecated: ## Note This alternative version of AlgorithmTraitConst::write_with_name function uses the following default values for its arguments:

fn empty(&self) -> Result<bool>

Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read

fn save(&self, filename: &str) -> Result<()>

Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).

fn get_default_name(&self) -> Result<String>

Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.
