MVREC: A General Few-shot Defect Classification Model Using Multi-View Region-Context

Shuai Lyu, Fangjian Liao, Zeqi Ma, Rongchen Zhang, Dongmei Mo, Waikeung Wong·December 22, 2024

Summary

MVREC, a few-shot defect classification model, addresses generalizability issues by focusing on specific datasets. It uses AlphaCLIP for feature extraction and a region-context framework to enhance defect features. MVREC introduces Zip-Adapter(-F) classifiers to cache visual features for few-shot classification. A new benchmark, MVTec-FS, based on MVTec AD, features 1228 defect images with instance-level mask annotations and 46 defect types. MVREC demonstrates effectiveness in general defect classification, incorporating contextual information for improved performance.
