Comparison of Visual Impression Given by Texture of Real Surfaces and Synthesized Images

We present a method to compare visual impressions given by the textures of real surfaces and 3D synthesized images of synthetic resins to improve the reality of CG images. We analyzed the structures of the visual impressions by conducting subjective evaluation experiments using real textures and generated images of the textures based on measurements of surface characteristics. We clarified the relationship between the visual impressions of the textures and the surface characteristics and showed the possibility of feedback to improve the reality of CG images.
