996    - lots of texture perception work on texture discrimination
997    
998    - we need also memorization; therefore, careful evaluation is needed
999    
1000    - experiments on abstract images and photographs
1001    
1002    - pilot test: 15 textures or pure colors shown sequentially, 5 seconds each.
1003      recognition tested by showing the 15 seen textures mixed with 15 new
1004      textures in a random order. subjects answers old/new.
1005    
1006    - results: for textures, 80 percent correct (12/15 correctly recognized
1007      as seen and 12/15 correctly identified as not seen).
1008      for pure colors, 53 percent correct (13/15 correctly recognized
1009      as seen and 3/15 correctly identified as not seen).
