consider as well the posting a while back by Peter Swinson regarding
"stochastic resonance," which pointed out that the perception of  
sharpness
may have nothing to do with resolution, but rather with noise level  
(some
noise being preferable to no noise).  So we have that factor as well as
resolution/definition (I still feel these last two are so close  
semantically
as be synonymous, after reading all the arguments for and against).
