Evaluation of Visual Preferences of 50 Japanese Wood Species Using Digital Images

Abstract

For the purpose of evaluating visual preferences for 50 Japanese wood species, the interval scale value of visual preferences by subjects whose age ranges from 19 to 30 years was determined by using a paired comparison method. Correlation analysis between the color attributes of each wood image and the interval scale values of preference showed that the preference had a strong positive correlation with the “coefficient of variation of R values in the RGB” and the “minimum value of R-value”, and a strong negative correlation with the “coefficient of variation of R value”. These results suggest that wood species which have strong redness with warm colors and wood grain that is not clear are visually preferred.
