Struct ChessConfig 

#[non_exhaustive]
pub struct ChessConfig {
    pub params: ChessParams,
    pub multiscale: CoarseToFineParams,
}

Unified detector configuration combining response/detector params and multiscale/pyramid tuning.

ChessConfig::default keeps the detector in the single-scale regime. Use ChessConfig::multiscale for the recommended coarse-to-fine starting point on high-resolution, small-board, or textured projected patterns.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

params: ChessParams

Low-level ChESS response/detector parameters (ring radius, thresholds, NMS radius, minimum cluster size, and subpixel refinement backend).

multiscale: CoarseToFineParams

Coarse-to-fine multiscale configuration (pyramid shape, ROI radius, merge radius).

Implementations

impl ChessConfig

pub fn multiscale() -> Self

Recommended coarse-to-fine starting point.

This uses the canonical r=5 ChESS ring together with:

• 3 pyramid levels,
• min_size = 128,
• coarse ROI radius 3,
• merge radius 3.0.

pub fn single_scale() -> Self

Convenience helper for single-scale detection.

This is equivalent to ChessConfig::default but kept as an explicit readability helper at call sites.

Trait Implementations

impl Clone for ChessConfig

fn clone(&self) -> ChessConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChessConfig

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

Formats the value using the given formatter.

impl Default for ChessConfig

fn default() -> ChessConfig

Returns the “default value” for a type.
