RGB色空間を用いた色彩テクスチャのカラーイメージと視覚的特徴の関係

摘要

Color feature analysis by using RGB color space was applied to the characterization of color textures of 15 kinds of fabrics including color and form information. The average (AVE), variance (VAR), angular second moment (ASM), contrast (CON), correlation (COR), entropy (ENT) and fractal dimension (D) statistically extracted from brightness distributions of RGB color images for fabrics, which were captured from a color scanner, were measured as visual feature parameters. The vivid-obscure, gaudy-plain, striking-subdued, dynamic-passive, distinct-vague, transparent-turbid, soft-hard, strong-weak, warm-cool, light-heavy and bright-dark feelings of color textures were evaluated using a sensory evaluation method by which either word was selected, and the relationship between their sensory evaluation values and the visual feature parameters was examined by factor analysis, which showed that dynamic feeling is related to VAR and COR, and light, strong, soft and bright feelings to AVE.%色彩は心理的に作用して，われわれの心に何らかの 感情や感覚，あるいはイメージを引き起こす．色彩と 感情や感覚，あるいはイメージとの結びつけは．色彩 心理の重要なテーマであるだけでなく，消費者の好き 嫌いを決定させる重要な役割を持っている．これまで 色彩が均一である色刺激に対して，色彩感情の分類と 色彩科学に基づいた色彩感情モデルの開発研究が数多 く行われ，色彩と印象や感情との関係が明確にされて きている.
