pub fn distance_transform_edt(mask: &BinaryMask) -> VisionResult<Image<f32, 1>>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.
