patchdist_score — SPC anomaly_patch op

• データ種: image2d × table → table
• 呼び出し: import fullseye as fs; fs.ledger.patchdist_score(image, model, smooth=4.0) (実装を直接呼ぶなら import anomaly_patch; anomaly_patch.patchdist_score(image, model, smooth=4.0)、台帳から引くなら opsspc.get("patchdist_score"))

使い方

Score one image against a per-position normal distribution: the Mahalanobis distance per patch (table).

model comes from patchdist_fit; image must have the training images’ shape. The grid of distances sqrt((x - mu)' P (x - mu)) is interpolated (bilinear, between patch centres) to the image size and smoothed by a Gaussian of smooth px (0 = no smoothing). Returns map (H, W; higher = more anomalous), grid (the raw distances), image_score (the maximum of the smoothed map) and smooth.

Raises ValueError for a model that is not a patchdist_fit result, a different image shape, or a negative / non-finite smooth.
