A Defect Detection Algorithm of Denim Fabric Based on Cascading Feature Extraction Architecture
Shuangbao Ma,Renchao Zhang,Yujie Dong,Yuhui Feng,Guoqin Zhang 한국정보처리학회 2023 Journal of information processing systems Vol.19 No.1
Defect detection is one of the key factors in fabric quality control. To improve the speed and accuracy of denimfabric defect detection, this paper proposes a defect detection algorithm based on cascading feature extractionarchitecture. Firstly, this paper extracts these weight parameters of the pre-trained VGG16 model on the largedataset ImageNet and uses its portability to train the defect detection classifier and the defect recognitionclassifier respectively. Secondly, retraining and adjusting partial weight parameters of the convolution layerwere retrained and adjusted from of these two training models on the high-definition fabric defect dataset. Thelast step is merging these two models to get the defect detection algorithm based on cascading architecture. Then there are two comparative experiments between this improved defect detection algorithm and otherfeature extraction methods, such as VGG16, ResNet-50, and Xception. The results of experiments show thatthe defect detection accuracy of this defect detection algorithm can reach 94.3% and the speed is also increasedby 1–3 percentage points.
