dataset structure setting

[Qi-Ran]

Hello, I would like to ask about the structure of the Real-IAD dataset, what specific images correspond to the 'OK' and 'NG' folders under each category? What do the 'AK', 'HS', 'PS', and other folders in the 'NG' folder represent? Why are these classifications made?

OK represents normal images, while NG represents anomalous images. AK, HS, PS, and others correspond to specific defect types. For more details, please refer to the descriptions in the paper.

I'm very sorry I found eight types of defects in the paper, but not the corresponding abbreviations
