A number of methods for automated objective ratings of fabric pilling based on image
analysis are described in the literature. The periodic structure of fabrics makes them
suitable candidates for frequency domain analysis. We propose a new method of frequency
domain analysis based on the two-dimensional discrete wavelet transform to objectively
measure pilling intensity in sample images. We present a preliminary evaluation of the
proposed method based on analysis of two series of standard pilling evaluation test
images. The initial results suggest that the proposed method is feasible, and that the ability
of the method to discriminate between levels of pilling intensity depends on the wavelet
analysis scale being closely matched to the fabric interyarn pitch. We also present a
heuristic method for optimal selection of an analysis wavelet and associated analysis
scale.
