Struct ChessConfig 

#[non_exhaustive]
pub struct ChessConfig {
    pub ring: ChessRing,
    pub descriptor_ring: DescriptorRing,
    pub nms_radius: u32,
    pub min_cluster_size: u32,
    pub refiner: ChessRefiner,
}

Configuration for the ChESS detector branch of DetectionStrategy.

Carries the detector ring choice, descriptor ring choice, NMS / clustering thresholds (in input-image pixels), and the subpixel refiner. Multiscale and upscale live at the top level of DetectorConfig and apply to both strategies.

Common knobs

• ring — choose the detector kernel radius.
• descriptor_ring — choose the descriptor sampling radius.
• refiner — select and configure the subpixel refinement backend.

Advanced tuning

nms_radius and min_cluster_size control NMS and peak filtering. The defaults work well across a wide range of image scales. Reduce nms_radius when corners are packed tightly; increase min_cluster_size to suppress isolated noise peaks.

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.

ring: ChessRing

Detector ring radius. Canonical selects the paper’s r=5, Broad selects r=10.

descriptor_ring: DescriptorRing

Descriptor sampling ring. Independent of the detector ring; FollowDetector mirrors the detector’s choice.

nms_radius: u32

Advanced tuning. Non-maximum-suppression half-radius in input-image pixels. Only the highest-response pixel within this radius is kept. Default is 2 (5×5 suppression window). Reduce when corners are closer together than 2·nms_radius pixels; increase to suppress near-duplicate detections on blurry images.

min_cluster_size: u32

Advanced tuning. Minimum number of positive-response neighbours within the NMS window that a candidate must have to be accepted. Default is 2. Increase to require a stronger local cluster of response, suppressing isolated noise peaks at the cost of potentially missing weak corners near image boundaries.

refiner: ChessRefiner

Subpixel refiner. Each variant carries its tuning struct.

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() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ChessConfig

where ChessConfig: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ChessConfig

fn eq(&self, other: &ChessConfig) -> 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 ChessConfig

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 ChessConfig
