Struct RadonConfig 

#[non_exhaustive]
pub struct RadonConfig {
    pub ray_radius: u32,
    pub image_upsample: u32,
    pub response_blur_radius: u32,
    pub peak_fit: PeakFitMode,
    pub nms_radius: u32,
    pub min_cluster_size: u32,
    pub refiner: RadonRefiner,
}

Configuration for the whole-image Radon detector branch of DetectionStrategy.

All radii and counts are in working-resolution pixels (i.e. after image_upsample). Multiscale and upscale live at the top level of DetectorConfig and apply to both strategies.

Common knobs

• refiner — select and configure the subpixel refinement backend.
• image_upsample — 2 (the default) reproduces the paper’s 2× supersampled detection; 1 is faster but less accurate on low-resolution inputs.

Advanced tuning

The remaining fields control low-level detection behaviour. The defaults reproduce the paper’s recommended settings and work well for typical camera images. Adjust them only when you have a specific reason (e.g. a non-standard image resolution or SNR budget).

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.

ray_radius: u32

Advanced tuning. Half-length of each Radon ray in working-resolution pixels. The ray has 2·ray_radius + 1 samples. Paper default at image_upsample = 2 is ray_radius = 4. Shorter rays are faster but integrate less signal; longer rays are more discriminating but may cross into neighbouring cells.

image_upsample: u32

Image-level supersampling factor applied before ray integration. 1 operates on the input grid; 2 (paper default) is equivalent to bilinearly upsampling the input first, giving sub-pixel ray positioning. Values ≥ 3 are clamped to 2 by the core detector.

response_blur_radius: u32

Advanced tuning. Half-size of the box blur applied to the Radon response map after integration. 0 disables blurring; 1 (default) yields a 3×3 box, smoothing quantisation noise in the response. Increase only on very high-SNR images where extra smoothing is unwanted.

peak_fit: PeakFitMode

Advanced tuning. Peak-fit mode for the 3-point subpixel refinement of the response-map argmax. Gaussian (default) fits on log-response (more accurate near the peak); Parabolic fits directly on the response values. See PeakFitMode.

nms_radius: u32

Advanced tuning. Non-maximum-suppression half-radius in working-resolution pixels. Default is 4. See ChessConfig::nms_radius for guidance; note that these pixels are at working resolution (after image_upsample).

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. See ChessConfig::min_cluster_size for guidance.

refiner: RadonRefiner

Subpixel refiner. Each variant carries its tuning struct.

Trait Implementations

impl Clone for RadonConfig

fn clone(&self) -> RadonConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RadonConfig

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

Formats the value using the given formatter.

impl Default for RadonConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RadonConfig

where RadonConfig: 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 RadonConfig

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

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 RadonConfig
