The Fractal Evaluation of Wood Texture by the Triangular Prism Surface Area Method

摘要: Textures of the surfaces fifteen wood species were characterized by fractal dimension triangular prism surface area method. Fractal ranged from 2 to 3, and sharp lightness variation caused high dimension, whereas low values related smooth variation. Based on this index, specimens generally divided into a hardwood group with value greater than 2.50 softwood less 2.50. Six types distribution explored in our experiments, including plane, inclined concave, convex, zigzag distribution, hilly distribution. From these both features local textures general tendency whole could be illustrated. It was strongly proposed that should adopted quantitatively evaluate texture coarseness evenness, because such number grains, orientation, location. For color matching, is great importance ensuring matching achieve constructed close natural These patterns considered as good reference previous matching. Little along grain observed, used simplify very limited indices. No significant relationship found between lightness, further implying independent lightness.
