Replacing PaDiM's random channel sampling with per-layer wavelet subband selection yields test-set-optimized MVTec AD averages of 99.32% Image-AUC and 92.10% Pixel-AUC, and shows LL bands help detection while detail bands help localization.

Wavelet-Enhanced PaDiM for Industrial Anomaly Detection
Replacing PaDiM's random channel sampling with per-layer wavelet subband selection yields test-set-optimized MVTec AD averages of 99.32% Image-AUC and 92.10% Pixel-AUC, and shows LL bands help detection while detail bands help localization.
