vol_rle_components — 3D rle_region op

• 数据种类:voxel → rle_region

• 调用: import fullseye as fs; fs.ledger.vol_rle_components(vol_binary, connectivity=26)(要直接调用实现,import volregion; volregion.vol_rle_components(vol_binary, connectivity=26);从台账取用则 ops3d.get("vol_rle_components"))

用法

把二值体拆成逐成分的 `VolRLE` 区域。

> 以下的详细说明为原文 —— 摘要与标题已翻译。

*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.
