Struct RadonDetectorParams 

#[non_exhaustive]
pub struct RadonDetectorParams {
    pub ray_radius: u32,

    pub response_blur_radius: u32,
    pub peak_fit: PeakFitMode,

Configuration for the whole-image Radon detector.

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

Half-length of each ray in working-resolution pixels (i.e. post-upsample). The ray has 2·ray_radius + 1 samples. Paper default at image_upsample=2 is 4 working pixels ⇒ 2 physical.

image_upsample: u32

Image-level supersampling factor. 1 operates on the input pixel grid; 2 bilinearly upsamples first (paper default). Supports the set {1, 2}; values >= 3 are clamped to 2 (the crate-internal MAX_IMAGE_UPSAMPLE). Higher factors are future work.

response_blur_radius: u32

Half-size of the box blur applied to the response map. 0 disables blurring; 1 yields a 3×3 box.

peak_fit: PeakFitMode

Peak-fit mode for the 3-point subpixel refinement.

threshold_rel: f32

Response threshold as a fraction of the per-frame maximum response. The Radon (max−min)² response is unnormalized (it scales with ray length and contrast), so a relative floor adapts across frames where a fixed absolute cutoff would not.

nms_radius: u32

Non-maximum-suppression half-radius (in working-resolution pixels).

min_cluster_size: u32

Minimum count of positive-response neighbours in the NMS window required to accept a peak. Rejects isolated noise.

Implementations

impl RadonDetectorParams

pub const DEFAULT_THRESHOLD_REL: f32 = 0.28

Default response threshold as a fraction of the per-frame maximum response. The Radon (max−min)² response is dense near zero, so the floor must sit well above the texture noise to keep only well-formed corners; this value is calibrated on the public reference images.

pub const DEFAULT_NMS_RADIUS: u32 = 4

Default non-maximum-suppression half-radius, in working-resolution pixels. Wider than the ChESS default to suit the wider Radon response peak. Single source of truth shared with the chess-corners facade’s Radon presets.

pub const DEFAULT_MIN_CLUSTER_SIZE: u32 = 2

Default minimum count of positive-response neighbours required to accept a cluster. Single source of truth shared with the chess-corners facade’s Radon presets.

Trait Implementations

impl Clone for RadonDetectorParams

fn clone(&self) -> RadonDetectorParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RadonDetectorParams

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

Formats the value using the given formatter.

impl Default for RadonDetectorParams

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RadonDetectorParams

where RadonDetectorParams: 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 RadonDetectorParams

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
