Abstract:

The large differences in texture and shape of the same type cloth and certain similarities between heterogeneous types result in the difficult classification of fabric defects. In this paper, it is proposed to select the fabric defect local region features and use the common vector method to extract features and to do classification. The defect local region features refer to the fabric defect local region gray histogram and geometrical features. First, we detect the fabric defect region by the optimal multiple-channels 2D Gabor wavelet| then select the features of the fabric defect local region gray histogram and geometrical feature (the rate of defect length and width, and the direction feature), and extract the common vector by the common vector algorithm| and finally, use the minimum distance method for defect classification. The algorithm is of small-sample learning, less computational load and high recognition rate.

Key words: fabric defect, histogram, geometrical feature, common vector, defect classification
