Automatic inspection of the warp-weft density using image processing techniques [Kumaş sikliklarinin görüntü i˙şleme tekni˙kleri˙ i˙le otomati˙k olarak belirlenmesi]

In this study,possibility of determining warp and weft yarn density of colored and figured plain and twill woven fabrics by wiener filter,median filter,grey level co-occurrence matrix and gray line profile methods,which are spatial techniques,and by fourier and wavelet transformation methods,which are frequency domain techniques,are investigated. considering the spatial techniques,the most successful technique that determines warp and weft densities of plain and twill fabrics is the median filter method. the following successful techniques are wiener filter and gray level co-occurrence matrix. on the other hand,it is obtained that fourier analysis method,one of the frequency domain techniques,which depends on the counting of the harmonics of the yarns,provide more successful result than spatial techniques.
