Analysis of wrinkle properties of fabrics using wavelet transform

金沢大学人間社会研究域学校教育系The decomposition and analysis of wrinkle profiles (signals) utilizing the wavelet transforms are presented. The Continuous Wavelet Transform (CWT) is used to analyze their wavelet coefficients C, which indicates the similarity closely correlated with the wavelet, and their wavelet power spectra. The signal can be decomposed into an approximation a5 and details dn with the Discrete Wavelet Transform (DWT), and 3-D images of the fabric wrinkles decomposed is obtained, proving a convenient format for the analysis of wrinkles and identifying the characterization of wrinkles. The analysis of wrinkle properties of AATCC replicas and fabrics are performed with this method. © 2008 The Textile Machinery Society of Japan
