Quantification of “Deep” in the Wood-grain Texture

Abstract

In this study, measurement experiment of physical properties of textures was conducted. To clarify the relation between the “deep” and physical characteristics, correlation analysis and multiple regression analysis were performed by using the data of past study. As a result, it turned out that the angle of 15° with respect to specular reflection light is related to “deep” when the viewpoint is static. Also, the dynamic viewpoint has more influence than the static viewpoint.
