     n 1: the feel of a surface or a fabric; "the wall had a smooth
          texture"
     2: the essential quality of something; "the texture of
        Neapolitan life"
     3: the musical pattern created by parts being played or sung
        together; "then another melodic line is added to the
        texture"
     4: the characteristic appearance of a surface having a tactile

texture
     
         A measure of the variation of the intensity of a
        surface, quantifying properties such as smoothness, coarseness
        and regularity.  It's often used as a {region descriptor} in
        {image analysis} and {computer vision}.
     
        The three principal approaches used to describe texture are
        statistical, structural and spectral.  Statistical techniques
        characterise texture by the statistical properties of the grey
        levels of the points comprising a surface.  Typically, these
        properties are computed from the grey level {histogram} or
        grey level {cooccurrence matrix} of the surface.
     
        Structural techniques characterise texture as being composed
        of simple primitives called "texels" (texture elements), that
        are regularly arranged on a surface according to some rules.
        These rules are formally defined by {grammar}s of various
        types.
     
        Spectral techiques are based on properties of the Fourier
        spectrum and describe global periodicity of the grey levels of
        a surface by identifying high energy peaks in the spectrum.
