Color effects on visually perceived surface roughness of leg with pantyhose

Purpose The purpose of this paper is to elucidate the influence of pantyhose color on the visually perceived surface roughness of a pantyhose covered leg, and to examine the resultant evaluation index. Design/methodology/approach A sensory evaluation of the visually perceived surface roughness of a leg model with typical pantyhose of various colors and apparent yarn count was performed among Japanese females along with a statistical analysis. The relationship between the visually perceived surface roughness of the leg with pantyhose and the characteristics of the visual information of the pantyhose which was obtained by image analysis were investigated. Findings The color of the pantyhose had a clear influence on the visually perceived surface roughness of a leg with pantyhose. The characteristics of the visual information of the leg with pantyhose, namely, the shape of the histogram on the luminance distribution proved to be useful as the evaluation index of the visually perceived surface roughness. Originality/value Development of a novel pantyhose with superior aesthetic performance that meets the requirements of the wearer can be expected to lead to an improvement in the quality and performance of hosiery. This paper provides the quantification of aesthetic performance of pantyhose.
