%global _description %{expand:
cc3d performs connected component labeling (CCL) on 2D and 3D binary and
multi-label images, using a 3D variant of the two-pass union-find algorithm
with decision trees. It handles 4/8-connectivity in 2D and 6/18/26-connectivity
in 3D, labels every distinct value of a multi-label volume in a single pass,
and provides helpers for extracting statistics, largest components and dust
removal.

The implementation is C++ with a Cython binding, so labeling large volumes
stays fast and memory-efficient.}
