Struct RadonConfig 

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

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

All radii and counts are in working-resolution pixels (i.e. after image_upsample). The shared NMS / clustering thresholds (crate::DetectionParams), multiscale, and upscale live at the top level of crate::DetectorConfig and apply to both strategies.

Common knobs

• 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.
