This paper describes peculiar qualitative effects occurring intexture appearance, resulting from the manipulation of theamount of textural microelements. Keeping fixed the texturallocal properties, the increase of microelements’ numberproduces a texture aspect more homogeneous and denser.Conversely, patterns filled by a small number of elementsexhibit a more salient subparts’ articulation, and the texturalmicrostructures increase in perceived local contrast, size anddetailedness. Those effects are discussed in terms ofeconomic principles governing the visual processing.
