Color Measurement of Segmented Printed Fabric Patterns in Lab Color Space from RGB Digital Images

Abstract

Colors of textile materials are the first parameter of quality evaluated by consumers and a key component considered in selecting printed fabric. In the textiles industry, digital printed fabric analysis is one of the basic elements in successfully utilizing a color mechanism scheme and objectively evaluating fabric color alterations. Precise color measurement, however, is mostly used in sample analysis and quality inspection which help to produce reproducible or similar product. It is important that for quality inspection, the color of the product should be measured as a necessary requirement of quality control whether the product is to be accepted or not. Presented in this study is an unsupervised segmentation of printed fabrics patterns using mean shift algorithm and color measurements over the segmented regions of printed fabric patterns. The results established a consistent and reliable color measurement of multiple color patterns and appearance with the established range without any interactions.

“…Patterns and specifics of RGB to CIELab conversion are described in [8]. CIELab is color-opponent space with coordinates L* (Lightness, at L* = 0 black color is displayed, and with L* = 180 diffused white color occurs), a* (value in range between redpositiveand greennegativecolors) and b* (range between yellowpositiveand bluenegativecolors).…”

Review of Printed Fabric Pattern Segmentation Analysis and Application

“…According to our research [54], computer vision in textile industries has developed to the point that viable applications such as image segmentation and pattern recognition technology have become enormous [55]. Many applications have indeed generated variability of computer vision products and services from the traditional human system to a sophisticated automated machine inspection [56].…”

“…The color of a textile material is often the first attribute evaluated by consumers and a key component considered in the selection of fabrics. Colors are precisely measured in quality inspection to produce reproducible products [5]. In quality control, the product color should be a requirement.…”

“…The color channel a* is in the range −128 to +127 corresponding to green to red. The color channel b* is in the range −128 to +127 corresponding to blue to yellow [5], [6].…”
