An evaluation method of human visual impressions in gray scale textures using morphological morphology is proposed. Variations of textures are generated by modifying repetitively arranged objects and configurations of the arrangements of original textures. The variations are presented to human respondents, and similarity of modified textures based on human impressions is evaluated. The results of the human evaluation are compared with the results of similarity evaluation based on image features. It shows that global features such as density, regularity and directionality of the point configurations have significant effects on human visual impressions and identification of textures. In case of a texture without significant characteristics on its point configuration, local features such as the shape of the objects have some effects on the visual impressions.
