vol_reduce_domain — 3D domain op

資料種類:voxel × voxelvoxel

呼叫: import fullseye as fs; fs.ledger.vol_reduce_domain(vol, domain)(要直接呼叫實作,import volops; volops.vol_reduce_domain(vol, domain);從台帳取用則 ops3d.get("vol_reduce_domain"))

用法

把體限制在 *domain* 遮罩內(HALCON `reduce_domain`,逐體素)。

> 以下的詳細說明為原文 —— 摘要與標題已翻譯。

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.
