Implements object localization using decision trees.

Implementations

impl Localizer

pub fn localize(&self, image: &GrayImage, roi: &Point3<f32>) -> Point2<f32>

Estimate object location on the image

Arguments

• image - Target image.
• roi - Initial location to start:
  • roi.x position on image x-axis,
  • roi.y position on image y-axis,
  • roi.z initial window size to search.

pub fn perturb_localize(
    &self,
    image: &GrayImage,
    roi: &Point3<f32>,
    rng: impl RngCore,
    nperturbs: usize
) -> Point2<f32>

Estimate object location on the image with perturbation to increase accuracy.

Arguments

• image - Target image.
• roi - Initial location to start:
  • roi.x initial position on image x-axis,
  • roi.y initial position on image y-axis,
  • roi.z initial window size (in pixels) to search.
• rng - Source for randomness.
• nperturbs - How many perturbations to make.

pub fn from_readable(readable: impl Read) -> Result<Self, Error>

Create localizer from a readable source.
