vol_rle_components — 3D rle_region op

• データ種: voxel → rle_region
• 呼び出し: import fullseye as fs; fs.ledger.vol_rle_components(vol_binary, connectivity=26) (実装を直接呼ぶなら import volregion; volregion.vol_rle_components(vol_binary, connectivity=26)、台帳から引くなら ops3d.get("vol_rle_components"))

使い方

Split a binary volume into per-component VolRLE regions.

The use case run-length regions exist for: holding every component of a segmentation as its own region at run-proportional cost, instead of one dense label volume or N dense masks. Uses the key structural fact that a run is x-connected, so a component label is constant along each run — the volume is labelled once (dense, same 6/18/26 semantics as volops.vol_label) and then each run is assigned by its first voxel’s label; no per-component dense mask is ever built.

Returns a list of VolRLE ordered by label id (1..n). An empty mask returns an empty list.
