Struct SiftFeature 

pub struct SiftFeature {
    pub x: f32,
    pub y: f32,
    pub scale: f32,
    pub orientation: f32,
    pub octave: i32,
    pub level: u32,
    pub response: f32,
}

One feature (in input-image pixel units, top-left pixel center = (0.5, 0.5)).

Fields

x: f32

x coordinate (pixels).

y: f32

y coordinate (pixels).

scale: f32

Scale σ (in input-image pixel units).

orientation: f32

Output orientation = (2π - θ_int) mod 2π.

octave: i32

Detection octave index.

level: u32

Detection level j within the octave (0..S).

response: f32

Refined DoG value.
