248    \subsection{Texture perception}
249    
250    Studies on texture perception has mostly concentrated on
251    texture discriminability.
252    
253    First experiments on computer-generated, unnatural textures
254    in the 60s (see, e.g, \cite{julesz62visualpattern}) lead to
255    proposals of texture discrimation models based on
256    $N$th order statistics of pixels and elaborate connectivity
257    structures of certain micropatterns.XXX
258    
259    Of cource, such models are not directly applicable on high-resolution
260    textures; some kind of filtering would be required to obtain the input.  
261    However, the filtering itself can also have good explanatory power
