Example: Gaussian Smoothing

This example is the Gaussian stage of the shared filter gallery. It constructs a deterministic scalar phantom, wraps it in ritk_image::Image<f32, _, 3>, and applies GaussianFilter::apply_native with a physical sigma of 2.0.

The figure compares the input with the smoothed image and the Canny edge map that consumes the same image boundary:

Source and command

Source: crates/ritk-filter/examples/book_filter_gallery.rs

cargo run -p ritk-filter --example book_filter_gallery -- \
  docs/book/figures/filter_gallery.svg

The image shape and spatial metadata are unchanged by the filter. The package tests cover native/generic parity; the committed SVG is the visual output of this example’s figure contract. Rerun the command after changing the example to regenerate the artifact from the computed values.
