voxel_to_mips — 3D transform op

Data kinds: voxelimages

Call: import fullseye as fs; fs.ledger.voxel_to_mips(vol) (to call the implementation directly, import match3d; match3d.voxel_to_mips(vol); from the registry, ops3d.get("voxel_to_mips"))

Usage

3-D → maximum-intensity projections along the three orthogonal directions. The entry point for applying 2-D methods (e.g. accel's 2-D NCC).

> The detailed description below is the original text — the summary and the headings are translated.

入力 `(D,H,W) に対し [max(axis=0), max(axis=1), max(axis=2)]` の list を返す。形は

それぞれ `(H,W)(軸 0=D を潰す)、(D,W)(軸 1=H を潰す)、(D,H)`(軸 2=W を潰す)、

dtype float64。値は入力の最大値そのまま(正規化しない)。負の値も max なので通り、

密度 0 の背景は 0 のまま。

形の検証は無い(2-D は `axis=2` で失敗し、4-D 以上は動いてしまう)ので、呼び手で次元を確かめる。

`match_mip_2d` はこの 3 枚に 2D NCC を掛けて 3D 位置を冗長推定する。任意視点の投影は

`render_volume_projection`(mode="mip")。
