Struct DistanceTransformWorkspace

Source

pub struct DistanceTransformWorkspace { /* private fields */ }

Expand description

Reusable host scratch storage for the unit-spacing exact distance transform.

The workspace makes allocation reuse explicit and never shares mutable state between calls. Grow it once for the largest expected image, then pass it to distance_transform_edt_into on the same worker thread.

Source §

impl DistanceTransformWorkspace

Source

pub const fn new() -> Self
