Firstly, multi-direction lights were projected on the pilled fabric surface and its pilling images were captured, which mixed with invariant fabric background texture and pilling profile information modulated by the variant light projections. The captured fabric pilling images were analyzed by independent component analysis method. Using the spectrum feature analysis method, the independent components belonging to the complicated fabric background texture were separated and the pilling images are reconstructed with the left components. The experimental results showed that this method can effectively separate the pilling image from complicated fabric texture, which provides one possibility for colored fabric pilling objective evaluation.展开更多
