Struct Keypoint2 

pub struct Keypoint2 { /* private fields */ }

One scale-space image keypoint in pixel coordinates.

Implementations

impl Keypoint2

pub fn try_new(x: f32, y: f32, response: f32) -> Result<Keypoint2, VisionError>

Creates an unoriented one-pixel keypoint with a detector response.

pub fn with_size(self, size: f32) -> Result<Keypoint2, VisionError>

Sets a positive finite feature diameter in pixels.

pub fn with_angle_degrees(self, angle: f32) -> Result<Keypoint2, VisionError>

Sets a finite orientation, normalized into [0, 360) degrees.

pub const fn with_octave(self, octave: i32) -> Keypoint2

Sets a scale-pyramid octave.

pub const fn with_class_id(self, class_id: i32) -> Keypoint2

Sets an optional detector- or application-defined class identifier.

pub const fn x(self) -> f32

Returns the horizontal pixel coordinate.

pub const fn y(self) -> f32

Returns the vertical pixel coordinate.

pub const fn size(self) -> f32

Returns the feature diameter in pixels.

pub const fn angle_degrees(self) -> Option<f32>

Returns the normalized orientation, or None when not estimated.

pub const fn response(self) -> f32

Returns the detector response; larger values are more salient.

pub const fn octave(self) -> i32

Returns the scale-pyramid octave.

pub const fn class_id(self) -> Option<i32>

Returns the optional application-defined class identifier.

Trait Implementations

impl Clone for Keypoint2

fn clone(&self) -> Keypoint2

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Keypoint2

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for Keypoint2

fn eq(&self, other: &Keypoint2) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
