Thai silk is a main export product of Thailand. Since it is a luxury and high-cost product, its quality must be controlled and guaranteed. Automatic defect detection of Thai fabrics especially for Thai silk then becomes an interesting research issue. This paper proposes a hybrid automatic defect detection method for Thai woven fabrics using convolutional neural networks (CNNs) combined with an artificial neural network (ANN). Original images and local homogeneity images are used for CNN training, and gray level co-occurrence matrix (GLCM) texture statistics are used for ANN training. The results from two CNNs and an ANN are then combined by voting. The experimental results show that the proposed hybrid method is superior to the conventional methods in terms of accuracy.
