fn into_raw(self) -> *mut c_void

Return an the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> *const c_void

Return the underlying raw pointer.

fn as_raw_mut(&mut self) -> *mut c_void

Return the underlying mutable raw pointer

impl Drop for Elliptic_KeyPoint

fn drop(&mut self)

Executes the destructor for this type.

impl Elliptic_KeyPointTrait for Elliptic_KeyPoint

fn as_raw_mut_Elliptic_KeyPoint(&mut self) -> *mut c_void

fn set_axes(&mut self, val: Size_<f32>)

the lengths of the major and minor ellipse axes

fn set_si(&mut self, val: f32)

the integration scale at which the parameters were estimated

fn set_transf(&mut self, val: Matx23f)

the transformation between image space and local patch space

impl Elliptic_KeyPointTraitConst for Elliptic_KeyPoint

fn as_raw_Elliptic_KeyPoint(&self) -> *const c_void

fn axes(&self) -> Size_<f32>

the lengths of the major and minor ellipse axes

fn si(&self) -> f32

the integration scale at which the parameters were estimated

fn transf(&self) -> Matx23f

the transformation between image space and local patch space

impl From<Elliptic_KeyPoint> for KeyPoint

fn from(s: Elliptic_KeyPoint) -> Self

Converts to this type from the input type.

impl KeyPointTrait for Elliptic_KeyPoint

fn as_raw_mut_KeyPoint(&mut self) -> *mut c_void

fn set_pt(&mut self, val: Point2f)

coordinates of the keypoints

fn set_size(&mut self, val: f32)

diameter of the meaningful keypoint neighborhood

fn set_angle(&mut self, val: f32)

computed orientation of the keypoint (-1 if not applicable); it’s in [0,360) degrees and measured relative to image coordinate system, ie in clockwise.

fn set_response(&mut self, val: f32)

the response by which the most strong keypoints have been selected. Can be used for the further sorting or subsampling

octave (pyramid layer) from which the keypoint has been extracted

fn set_class_id(&mut self, val: i32)

object class (if the keypoints need to be clustered by an object they belong to)

impl KeyPointTraitConst for Elliptic_KeyPoint

fn as_raw_KeyPoint(&self) -> *const c_void

fn pt(&self) -> Point2f

coordinates of the keypoints

fn response(&self) -> f32

the response by which the most strong keypoints have been selected. Can be used for the further sorting or subsampling

fn octave(&self) -> i32

octave (pyramid layer) from which the keypoint has been extracted

fn class_id(&self) -> i32
