 We have conducted a pilot experiment (with one subject) 
 in a similar setting comparing
-the recognition performance of our textures with pure color backgrounds.
-First, 15 textures (or pure colors) were shown sequentially, 5 seconds each.

 The results were as follows: 
 for textures, 80 percent correct (12/15 correctly recognized
 as seen and 12/15 correctly identified as not seen);
 for pure colors, 53 percent correct (13/15 correctly recognized
 as seen and 3/15 correctly identified as not seen).

+Of course, this result is not statistically significant,
 but in conjunction with our experiences, it suggests that the
 textures are quite recongizable and that they are clearly
 superior to pure colors in terms of recognizability.
 
 Furthermore, the experiment only measured the ability to 
 recognize previosly seen textures within unseen textures.

 - as per Zipf's law [XXXref], it suffices to learn the textures 
   of the most recurring documents.
