Abstract(in English) There has been a great deal of research on appearance inspection using deep learning, which learns only from normal images. Recently, datasets incorporating not only structural anomalies such as scratches and stains, but also logical anomalies such as wrong number of parts and wrong combination of parts have been released, and there is a need to deal with such anomalies. In this study, we propose that PatchCore, a SOTA method for structural anomalies, can deal with logical anomalies by adding the consideration of consistency in the number of patches. Specifically, the histograms of the features of the test image and the good image are compared, and if there is a difference, it is considered as an anomaly. Experiments are conducted on a set of images with logical anomalies added to MVTec AD to verify the effectiveness of the proposed method.
