tid2013_evaluate — IMGMETRICS `iqa` op

• Data kinds: any × any → table

• Call: import fullseye as fs; fs.ledger.tid2013_evaluate(root, fn: 'Callable[[np.ndarray, np.ndarray], float]', *, subset=None, luma: 'str' = 'limited_u8', index: 'Optional[dict]' = None) -> 'dict' (to call the implementation directly, import iqatid; iqatid.tid2013_evaluate(root, fn: 'Callable[[np.ndarray, np.ndarray], float]', *, subset=None, luma: 'str' = 'limited_u8', index: 'Optional[dict]' = None) -> 'dict'; from the registry, opsimgmetrics.get("tid2013_evaluate"))

Usage

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

自前の指標 `fn(ref, dist) -> float` を TID2013 の組に当て、MOS との順位相関を返す。

`luma = "limited_u8"(作者規約の Y′ uint8 (H, W) を渡す、psnr.txt / ssim.txt と比べるとき)/ "rgb"`(uint8 (H, W, 3) を

そのまま渡す、psnrc.txt と比べるとき)。`subset = None`(3000 組全部)/ 個数(台帳の先頭 n)/ 名前の列(大文字小文字無視、

拡張子は任意)。参照画像は 25 枚を一度だけ読む。

返り値: `values (n,)、mos (n,)、idx(台帳の行番号)、names、srocc、krocc(τ_b)、n、n_inf、luma、seconds`。

`fn が inf` を返すのは正当(PSNR の完全一致)。TID2013 では歪み 18「彩度変化」の 125 組のうち **106 組で Y′ が参照と

1 画素も変わらず、作者は psnr.txt にその行を 100000.0** と書き、ssim.txt は 1.0(:func:tid2013_compare の `inf_as`)。

順位相関では inf を最大の順位として扱う。Raises `ValueError: luma が未知、fn` が数か ±inf を返さない(nan は拒否)、subset が不正。
