- Abstract:
-
In order to solve the problems,such as low efficiency,poor real-time performance and so on,in on-line detection of glass fiber fabric,a new method of fabric defect detection based on Blob analysis is proposed. Firstly,the image is smoothed by using mean filter,and the noises and the fabric textures are weakened. Then,the Otsu algorithm is used to find the best threshold to segment the image into Blob and background pixels. The shape of the Blob region is adjusted by using morphological processing. Finally,the connectivity analysis and feature extraction of the image are carried out. The number and size of the defects are obtained by using the least square fitting of the Blob region. Experimental results show that the method is simple,reliable and robust.
