%X According to the spectrum of fabric texture and defects, a new method for defect detection was presented. Firstly, on the basis of the fabric texture classification, a spectrum image was derived from the Fast Fourier Transform (FFT). Then, the frequency filter was designed to remove normal texture information, and the acquired reconstruction images were segmented into many sub-windows, in which variances were calculated as characteristics. Lastly, the characteristics were compared with the standard threshol...
