This study proposes a novel analysis system for printed fabrics that can automatically make color separation and identify repeat patterns. The system uses a scanner to obtain red, green and blue (RGB) color images of printed fabrics and then convert them into hue, saturation, intensity (HSI) color images. In order to obtain color separation, a genetic(More)
In a multicomponent nematic liquid crystal (NLC) mixture of a liquid crystal (negative-type NLC) and a photosensitive acrylic prepolymer, photopolymerization upon UV irradiation induces the separation of the LC and photosensitive acrylic prepolymer layers, thereby leading to a vertical arrangement of LC molecules. In this study, we propose a simple vertical(More)
