AB - The high-speed fabric defect detection algorithm based on fabric image layered model is proposed to
achieve the goal of accurate defect detection in the fabric production process. The image layered model
assumes that fabric image is a superposition of the periodic texture background image, noise image,
and defect image. Thus fabrics can be divided and conquered. Firstly, image preprocessing and mean
sampling algorithms were used to suppress the background texture and interference image layer, and
variances sampling was used for enhancing defect image layer. Secondly, the Otsu method was applied
for determining the segmentation threshold to segment the defect image automatically, then clear and
accurate defect image was obtained via image post-treatment algorithm. Finally, defect positions were
marked by a labeling algorithm to prepare for subsequent offine processing. Experiments on common
defect images from a standard defect library were described, and experimental results show that the
proposed algorithm based on image layered model is reliable, accurate, real-time and well used in the
industrial field.
