Struct MarkerScalePrior 

pub struct MarkerScalePrior {
    pub diameter_min_px: f32,
    pub diameter_max_px: f32,
}

Scale prior for marker diameter in detector working pixels.

The detector uses this range to derive proposal radii, outer-edge search windows, ellipse validation bounds, and completion ROI. When the marker scale prior is set via DetectConfig::set_marker_scale_prior or a constructor, all scale-dependent parameters are auto-derived.

A single known size can be expressed with MarkerScalePrior::from_nominal_diameter_px. For scenes where markers vary in apparent size, use MarkerScalePrior::new with a range.

Fields

diameter_min_px: f32

Minimum expected marker outer diameter in pixels.

diameter_max_px: f32

Maximum expected marker outer diameter in pixels.

Implementations

impl MarkerScalePrior

pub fn new(diameter_min_px: f32, diameter_max_px: f32) -> Self

Construct a scale prior from a diameter range in pixels.

pub fn from_nominal_diameter_px(diameter_px: f32) -> Self

pub fn diameter_range_px(self) -> [f32; 2]

Return the normalized diameter range [min, max] in pixels.

pub fn nominal_diameter_px(self) -> f32

Return nominal diameter (midpoint of [min, max]) in pixels.

pub fn nominal_outer_radius_px(self) -> f32

Return nominal outer radius in pixels.

pub fn normalized(self) -> Self

Return a normalized copy with finite, ordered, non-degenerate bounds.
