Abstract:

This paper deals with the efficiency evaluation of selected methods for automatic assessing of weaving density based on image analysis for different kinds of fabrics. A set of woven fabrics samples in plain, satin and twill weave and patterned fabrics were selected for assessing weave density. Images of samples were captured by a flat scanner followed by preprocessing for the enhancement of images. The methods selected included the gray line profile method, a method based on image decomposition with a Wiener and median filter, a method based on the co-occurrence matrix and one using the 2 dimensional discrete Fourier transform. The results show that any of these methods is suitable for all kinds of fabrics in general.
