Abstract
A new objective fabric pilling grading method based on wavelet texture analysis was
developed. The new method created a complex texture feature vector based on the wavelet
detail coefficients from all decomposition levels and horizontal, vertical and diagonal
orientations, permitting a much richer and more complete representation of pilling texture in
the image to be used as a basis for classification. Standard multi-factor classification
techniques of principal components analysis and discriminant analysis were then used to
classify the pilling samples into five pilling degrees. The preliminary investigation of the
method was performed using standard pilling image sets of knitted, woven and non-woven
fabrics. The results showed that this method could successfully evaluate the pilling
intensity of knitted, woven and non-woven fabrics by selecting the suitable wavelet and
associated analysis scale.
