Modeling the Relationship between Impressions and Image Features of Crinkle Finish of DSLR Camera

Abstract

In this article, the authors study the relationships between the principal impressions of crinkle-finished surfaces, which are found on camera exteriors, and the characteristics of test images of crinkle-finished surfaces. They extracted impression words for the surfaces through subjective experiments with humans. The results suggest that the impression is affected by five factors: two physical impression factors and three emotional impression factors. The surface images were obtained using a multi-angle measurement system that was built to collect images under various conditions. The authors used stepwise multiple regression to derive equations to predict the impressions of the surface given the characteristics of its test images. The results of the equations are highly correlated with the subjective scores of the five impression factors. These models will enable designers to design attractive crinkle-finished surfaces and camera exteriors. c © 2020 Society for Imaging Science and
