TLDR
For the removal of the noise from the binary fabric image the morphological opening operation with the suitable structuring element is performed and 94.08% success rate of detection of defects is achieved.Abstract:
In this paper a new approach for the detection of defects in woven fabric is presented where the singular value decomposition (SVD) method is used. SVD basically removes the interlaced grating structure of the waft and warp of the fabric leaving aside the defective part of the fabric. An intensity threshold value along with the module of definite size is considered for the binarization of the background free fabric image. Finally, for the removal of the noise from the binary fabric image the morphological opening operation with the suitable structuring element is performed. The technique is tested on 287 fabric samples consisting of five different types of defects in three types of woven fabrics from TILDA database. 94.08% success rate of detection of defects is achieved.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.

Detection of defects in fabrics using subimage-based singular value decomposition

TL;DR: Matrix singular value decomposition technique is employed for the detection of defects in fabrics by reducing the computational duty of operating over the whole image and removing the interlaced warp–weft grating structure from ROI.

The algebraic basis of mathematical morphology. I. dilations and erosions
TL;DR: It turns out that the basic operations called dilation and erosion are adjoints of each other in a very specific lattice sense and can be completely characterized if the automorphism group is assumed to be transitive on a sup-generating subset of the complete lattice.

FDAS: A Knowledge-based Framework for Analysis of Defects in Woven Textile Structures
TL;DR: In this article, a novel scheme for their classification based on their visual attributes is proposed, which can serve as the underlying framework for a vision-based inspection system, and the resulting knowledge-based system (FDAS) identifies defects, assigns probable causes for the defects, and suggests plausible remedies to avoid them.

Multivariate feature extraction from textural images of bread
TL;DR: The techniques presented in this paper define algorithms applied on the raw image without extensive preprocessing and show that mathematical transformations of images on a vectorised form will easily enable the use of multivariate techniques and possibly model several features hidden in the images at the same time.
