Abstract:

For more objective evaluation of fabric pilling, we try to use image processing technology to solve this problem. First, the standard pilling images of the smooth surface of worsted fabric (GB/T4802.3—2008) are scanned, and Fourier transform is used to filter the low frequency areas which represent the texture of fabric in the frequency domain. The filtered standard images can be obtained with inverse Fourier transform. Then the enhanced OTSU local threshold is applied to enhance pilling information, extract the pilling area, and calculate the proportion of the pilling area accouting for the total. On this basis, the relation between the proportion of the pilling area accouting for the total and grades of pilling of fabrics is established. Finally, feasibility of this method is verified by the analysis of actual fabric.
