Struct ThresholdEngine 

pub struct ThresholdEngine {
    pub tile_size: usize,
    pub min_range: u8,
}

Adaptive thresholding engine using tile-based stats.

Fields

tile_size: usize

Size of the tiles used for local thresholding statistics.

min_range: u8

Minimum intensity range for a tile to be considered valid.

Implementations

impl ThresholdEngine

pub fn new() -> Self

Create a new ThresholdEngine with default settings.

pub fn from_config(config: &DetectorConfig) -> Self

Create a ThresholdEngine from detector configuration.

pub fn compute_tile_stats<'a>( &self, arena: &'a Bump, img: &ImageView<'_>, ) -> BumpVec<'a, TileStats>

Compute min/max statistics for each tile in the image. Optimized with SIMD-friendly memory access patterns and subsampling (stride 2).

pub fn apply_threshold( &self, arena: &Bump, img: &ImageView<'_>, stats: &[TileStats], output: &mut [u8], )

Apply adaptive thresholding to the image. Optimized with pre-expanded threshold maps and vectorized row processing.

pub fn apply_threshold_with_map( &self, arena: &Bump, img: &ImageView<'_>, stats: &[TileStats], binary_output: &mut [u8], threshold_output: &mut [u8], )

Apply adaptive thresholding and return both binary and threshold maps.

This is needed for threshold-model-aware segmentation, which uses the per-pixel threshold values to connect pixels by their deviation sign.

Trait Implementations

impl Default for ThresholdEngine

fn default() -> Self

Returns the “default value” for a type.
