Function distance_transform_edt
pub fn distance_transform_edt(
mask: &BinaryMask,
) -> Result<Image<f32, 1>, VisionError>Expand description
Computes the exact Euclidean distance from every foreground pixel to the nearest background pixel using unit pixel spacing.
Background pixels have distance zero. A non-empty mask must contain at least one background pixel; otherwise the finite distance is undefined and an error is returned. The implementation applies the separable linear-time squared-distance transform by Felzenszwalb and Huttenlocher.
