TLDR
An approach for the fabric defects extraction in an image based on the theories of singular value decomposition is given, and the corresponding algorithm is proposed.Abstract:
Singular value decomposition technique is widely employed in feature analysis due to its strong capability of feature expression. Aiming at detection of fabric defects, this paper gives an approach for the fabric defects extraction in an image based on the theories of singular value decomposition, and proposes the corresponding algorithm. Firstly, singular value decomposition is performed on sub-image of the entire image, size of a rectangle window so that the average of singular values of every sub-image is obtained. Then, according to last step the average of singular values of all of sub-image is calculated. Finally the fabric image is segmented by means of a threshold related to the average of singular values and the defects could be detected. By using singular value decomposition, the complexes of operation are reduced, and noise issues of the image may be overcome. Validity and feasibility of this approach is proved through several experiments of fabric defects detection.read more

Textile fabric defect detection based on low-rank representation
TL;DR: A novel and robust fabric defect detection method based on the low-rank representation (LRR) technique, implemented by dividing a image into some corresponding blocked matrices to reduce dimensions and applying eigen-value decomposition on blocked matrix instead of singular value decomposition (SVD) on original fabric image, which improves the accuracy and efficiency.
