vx_warp_affine — VX geometry op

• Data kinds: image2d × matrix → image2d

• Call: import fullseye as fs; fs.ledger.vx_warp_affine(image, matrix, *, interpolation, border, constant_value=0) (to call the implementation directly, import vxcore; vxcore.vx_warp_affine(image, matrix, *, interpolation, border, constant_value=0); from the registry, opsvx.get("vx_warp_affine"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

アフィン変換(3.56 節)。逆写像: 出力の画素 (x, y) は入力の (x0, y0) から取る(REQ-0498):

`x0 = M[0,0]·x + M[0,1]·y + M[0,2]、y0 = M[1,0]·x + M[1,1]·y + M[1,2]`。

*matrix*: 数学の並びの 2×3(1 行目が x0 の係数 a, b, c)。★規格の C の宣言は `mat[3][2] = { {a,d}, {b,e}, {c,f} }`

(転置した並び)—— C の配列をそのまま渡すと形が (3, 2) になるので止める。*interpolation*(必須): `"nearest" / "bilinear"`。

*border*(必須): `"constant"(*constant_value* で埋める)/ "undefined"`(0 で埋める、値は規格上未定義)。

Raises `ValueError`: U8 の 2-D でない / matrix が 2×3 の有限でない / interpolation・border が一覧に無い。

• 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.

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
