vx_table_lookup — VX `pixel` op

• Data kinds: image2d × signal → image2d

• Call: import fullseye as fs; fs.ledger.vx_table_lookup(image, table, *, offset=0) (to call the implementation directly, import vxcore; vxcore.vx_table_lookup(image, table, *, offset=0); from the registry, opsvx.get("vx_table_lookup"))

Usage

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

表引き(3.47 節): 出力 = table[画素値 + offset] (REQ-0421)。U8 と S16 を受ける(REQ-0422)。出力の dtype は表の dtype。

*offset*: S16 の表は負の画素値を引くために中央を 0 に置く(VX_LUT_OFFSET、典型は 32768)。U8 は 0。

★表の外を引く画素があれば止める(黙って端に寄せない)。

Raises `ValueError`: 画像が U8/S16 の 2-D でない / 表が 1-D でない・空 / 表の外を引く画素がある。
