In the first step, the observed matrix X is constructed from a large number of defect-free sub-images and PCA is operated to achieve dimension reduction. In the second step, the transformation matrix W and independent basis subspace s are obtained from defect-free sub-images through ICA. In the final step, feature extraction is achieved from the overlapping sub-windows of a test image. Then a sub-window is classified as defective or nondefective according to Euclidean distance. The results have been analyzed in detail and illustrated this approach has better performance in raw textile.
