Struct ThresholdAlgorithm 

pub struct ThresholdAlgorithm { /* private fields */ }

Threshold-based glint detection algorithm

This algorithm identifies glint pixels by applying threshold values to each band of the image. A pixel is marked as glint if any band exceeds its corresponding threshold value.

The algorithm uses a disjunctive approach: if any band at a pixel location exceeds its threshold, that pixel is marked as glint.

Implementations

impl ThresholdAlgorithm

pub fn new(thresholds: Vec<f64>) -> Result<Self>

Create a new threshold algorithm with the given threshold values

Arguments

• thresholds - Threshold values for each band, must be in range [0.0, 1.0]

Example

use glint_mask_tools::algorithms::ThresholdAlgorithm;

// RGB thresholds: stricter for blue (glint often appears in blue),
// less strict for red and green
let algorithm = ThresholdAlgorithm::new(vec![0.9, 0.8, 0.7])?;

pub fn uniform(threshold: f64, band_count: usize) -> Result<Self>

Create a threshold algorithm with uniform thresholds for all bands

Arguments

• threshold - Single threshold value to use for all bands
• band_count - Number of bands to create thresholds for

pub fn thresholds(&self) -> &[f64]

Get the threshold values

pub fn band_count(&self) -> usize

Get the number of bands this algorithm expects

pub fn set_thresholds(&mut self, thresholds: Vec<f64>) -> Result<()>

Set new threshold values

pub fn set_band_threshold( &mut self, band_index: usize, threshold: f64, ) -> Result<()>

Update a specific band’s threshold
