domain op• 数据种类:voxel × voxel → voxel
• 调用: import fullseye as fs; fs.ledger.vol_reduce_domain(vol, domain)(要直接调用实现,import volops; volops.vol_reduce_domain(vol, domain);从台账取用则 ops3d.get("vol_reduce_domain"))
把体限制在 *domain* 掩码内(HALCON `reduce_domain`,逐体素)。
> 以下的详细说明为原文 —— 摘要与标题已翻译。
Every voxel outside the foreground of *domain* is set to `0` — the same
"outside the domain is undefined -> 0" convention the 2-D `it_crop_domain`
op uses (a plain numpy array cannot carry a separate domain channel, so the
restriction is materialised). A non-`{0, 1}` *domain* is thresholded at
`> 0.5`. Use it to silence everything a downstream operator must not see
(metal artefacts, the scanner bed, a neighbouring part); combine with
:func:vol_crop_domain when you also want the *memory* of the volume
reduced, not just its values.
Returns a `(D, H, W)` float64 volume of the same shape.
