Struct cv::feature::akaze::KeyPoint

pub struct KeyPoint {
    pub point: (f32, f32),
    pub response: f32,
    pub size: f32,
    pub octave: usize,
    pub class_id: usize,
    pub angle: f32,
}

A point of interest in an image. This pretty much follows from OpenCV conventions.

Fields

point: (f32, f32)

The horizontal coordinate in a coordinate system is defined s.t. +x faces right and starts from the top of the image. the vertical coordinate in a coordinate system is defined s.t. +y faces toward the bottom of an image and starts from the left side of the image.

response: f32

The magnitude of response from the detector.

size: f32

The radius defining the extent of the keypoint, in pixel units

octave: usize

The level of scale space in which the keypoint was detected.

class_id: usize

A classification ID

angle: f32

The orientation angle
