A novel digital imaging method for measuring cashmere color and its application

Abstract: The quality of cashmere, such as color and length, determines its price and application. In the current cashmere inspection system, color and length are tested by visual assessment, which is a subjective, time- and labor-consuming process. Herein, the goal of this research is to develop a new method of testing cashmere color using image analysis, and to study the application of color in length measurement. During the color measurement, cashmere was prepared under two sample placement methods, and color feature… Show more

“…Such Random-beard Image Method (RBIM) was declared for wool fiber length with widening and stable clamping dual-beard Wu and Wang 2019), and the above derived K-M theory with an ideal R∞ of grayscale transmission images transformed from spectrophotometer, which was validated for the applications of wool fibrogram and fiber length. The introduced reflectance image and ideal R∞ of the greyscale channel were established by a conversion model between color luminance (L) (Heng et al 2021), which was reduced from data of spectrophotometer for natural cashmere fiber length. However, this ideal R∞ was only adaptable for natural cashmere with a narrow color gamut due to the more extensive light wavelength range using the grey channel because of ignoring the iris and noise on the light propagation route.…”

“…Many scholars have used image analysis to detect the color of textile fabrics, and different color perception matching models have been proposed for different fabrics. For example, in the literature, Heng et al 27 developed a new method to detect the color of cashmere using image analysis and studied the application of color in length measurement. In the literature, Zhang and Xiong 28 proposed a method for color perception and recognition of Cantonese embroidery images based on a discrete mathematical model.…”

“…Therefore, a color luminance ( L ) and infinite-thickness reflectance ( R ∞ ) conversion model was established for light-color natural cashmere fiber length. 45,46 However, this ideal tested R ∞ includes reflections of light at the interface with air, different from the assumed reflectance of the K–M law, defined as theoretical reflectance here. Hence, further studies are needed for the algorithm of linear optical densities.…”
