Weaving Density Evaluation with the Aid of Image Analysis

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.Center of Quality and Reliability (CQR) [1M06047
