link_edges — 3D `edges` op

• Data kinds: voxel → voxel

• Call: import fullseye as fs; fs.ledger.link_edges(edge_mask) (to call the implementation directly, import edges3d; edges3d.link_edges(edge_mask); from the registry, ops3d.get("link_edges"))

• Return value through the ledger: fullseye.ledger.link_edges(...) returns **only the declared out type voxel** (the underlying function also returns auxiliary values). When you need what was dropped, use fullseye.ledger.link_edges.raw(...) or call edges3d.link_edges directly.

• Underlying return: (linked, n)

Usage

Label an edge mask into connected components with 26-neighbour connectivity.

Parameters

----------

edge_mask : (D,H,W) bool

Returns

-------

labels : (D,H,W) int

各 voxel の成分ラベル(背景 = 0、成分 = 1..n)。

n : int

連結成分数。

Notes

-----

26 連結(3x3x3 の全近傍)。断片化したエッジ片を 1 本の曲線 / 閉曲面としてまとめ、

下流の Hough / chamfer で成分単位に扱えるようにする。
