Enum MultiscaleConfig 

#[non_exhaustive]
pub enum MultiscaleConfig {
    SingleScale,
    Pyramid {
        levels: u8,
        min_size: usize,
        refinement_radius: u32,
    },
}

Coarse-to-fine multiscale configuration.

JSON shape mirrors Threshold and UpscaleConfig:

• { "single_scale": null } — run the detector once on the full image.
• { "pyramid": { "levels": 3, "min_size": 128, "refinement_radius": 3 } } — build an image pyramid, detect seeds on the coarsest level, and refine each seed into the base image. Honoured by both ChESS and Radon strategies.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SingleScale

Single-scale detection (no pyramid).

Pyramid

Coarse-to-fine pyramid detection.

Fields

levels: u8

Number of pyramid levels (≥ 1). Level 0 is the base image; each subsequent level is a 2× box-filter downsample.

min_size: usize

Minimum short-edge length in pixels. The pyramid stops once the next level would fall below this size.

refinement_radius: u32

ROI half-radius at the coarse level used to refine each seed into the base image, in coarse-level pixels.

Implementations

impl MultiscaleConfig

pub const fn pyramid_default() -> Self

Three-level pyramid with library defaults (min_size = 128, refinement_radius = 3). Equivalent to the multiscale preset used by DetectorConfig::chess_multiscale and DetectorConfig::radon_multiscale.

pub const fn pyramid( levels: u8, min_size: usize, refinement_radius: u32, ) -> Self

Pyramid with caller-supplied parameters.

Trait Implementations

impl Clone for MultiscaleConfig

fn clone(&self) -> MultiscaleConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MultiscaleConfig

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

Formats the value using the given formatter.

impl Default for MultiscaleConfig

fn default() -> MultiscaleConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MultiscaleConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MultiscaleConfig

fn eq(&self, other: &MultiscaleConfig) -> 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.

impl Serialize for MultiscaleConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for MultiscaleConfig
