antialias — 3D render op

Data kinds: image2dimage2d

Call: import fullseye as fs; fs.ledger.antialias(hi_res_image, ss, filter: 'str' = 'box') -> 'np.ndarray' (to call the implementation directly, import render_ssaa; render_ssaa.antialias(hi_res_image, ss, filter: 'str' = 'box') -> 'np.ndarray'; from the registry, ops3d.get("antialias"))

Usage

Downscale a high-resolution image by an integer factor `ss` (area-average anti-aliasing).

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

`hi_res_image(H*ss, W*ss) または (H*ss, W*ss, C)` の float 画像。各

`ss×ss ブロックを重み付き平均して (H, W[, C]) を返す。filter`:

• `"box"` — 等重み平均(正確な面積平均、SSAA の標準)。

• `"gauss"` — ブロック中心を重く見るガウス重み(σ = ss/2、僅かに柔らかい)。

Fail-closed: `ss は 1 以上の整数、入力は 2D / 3D、各辺は ss` で割り切れること。

非有限値があれば `ValueError`(平均で NaN が伝播しないよう確保前に拒否)。

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.
