  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
 
  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.
