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 |
