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 crate::UpscaleConfig:

• "single_scale" — 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 (integer >= 1, at most 255). Level 0 is the base image; each subsequent level is a 2× box-filter downsample.

min_size: usize

Minimum short-edge length of a pyramid level, 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 (integer >= 0).

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 crate::DetectorConfig::chess_multiscale and crate::DetectorConfig::radon_multiscale.

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

Pyramid with caller-supplied parameters.
