A model for the cloudiness of fabrics, H. Neunzert (Ed.), Progress in industrial mathematics at ECMI 94, Wiley-Teubner, Chichester, 258-265, 1996.
Cloudy inhomogenities in artificial fabrics are graded by a fast method which is based on a Laplacian pyramid decomposition of the fabric image. This band-pass representation takes into account the scale character of the cloudiness. A quality measure of the entire cloudiness is obtained as a weighted mean over the variances of all scales.
