Comprehensive Evaluation Method of Ethnic Costume Color Based on K-Means Clustering Method

Abstract

Color is the external manifestation of ethnic minority culture, and the costume of each ethnic group has its objective color matching rules. In the color design of minority costumes, there is often a lack of scientific evaluation methods. Aiming at this problem, this article proposed a comprehensive evaluation method, based on the K-Means clustering method, for evaluating color matching schemes of minority costumes. We used the K-Means clustering method to analyze the objective laws of minority costume colors, and based on the objective laws found, we extracted the objective evaluation indicators. With the AHP (analytic hierarchy process) method, the judgment matrix was established to obtain the relative weights of each cultural image and objective evaluation indicator. Based on the trapezoidal fuzzy number, the user’s evaluation value of the cultural image index was clarified. The GRA-TOPSIS evaluation method was introduced to rank the color matching schemes of minority costumes. Taking the evaluation of the color matching scheme of Yi costumes as an example, this article confirmed that the proposed comprehensive evaluation method can effectively screen out the color matching schemes with the characteristics of minority costumes and can rank the color schemes to be evaluated according to their relative similarity degree to the color characteristics of minority costumes. The method integrated subjective and objective evaluations, overcame the problem of contradictory results of subjective and objective evaluations, and achieved a certain degree of symmetry between the objectivity of the color laws of minority costumes and the subjectivity of the cultural image of minority costumes. In addition, we also found the possibility of using K-Means clustering to extract the main color features of minority costumes to improve the design of color schemes.

“…Thompson et al [38] proposed a novel color quantization (CQ) method based on the online k-means formula, using adaptive and efficient cluster center initialization and quasi-random sampling to achieve deterministic, rapid, and high-quality quantization [39]. By integrating the Analytic Hierarchy Process (AHP), Zhao et al [40] introduced the GRA-TOPSIS evaluation method to rank and rate ethnic minority costume color schemes, finding KMA beneficial for refining color scheme designs. Based on KMA, Basar et al [41] introduced an innovative adaptive initialization technique in RGB histogram analysis to determine the number of clusters and locate initial cluster centroids, assisting the standard k-means algorithm in tackling color image segmentation challenges.…”

“…It was used to help the company re-plan the color scheme of its wardrobe products. Zhao et al [17] utilized the K-Means clustering method to analyze the objective law of Yi costume colors. Based on the features of Yi costume's primary colors in the HSV color space, they proposed objective evaluation indicators to evaluate the color scheme and help improve it.…”

“…In the context of image color extraction, statistical analysis methods such as clustering algorithms (e.g., K-Means and DBSCAN algorithms) are commonly employed. Zhao et al used the K-means clustering method to analyze the color patterns of Yi clothing, and transformed the corresponding color patterns into objective evaluation indicators [14]. Tian et al used a developed Kmeans clustering algorithm to classify the surface color of buildings after extracting them from their background environment [15].…”
