[Blindmath] Facial recognition -- food for thought

Thu Mar 29 01:49:53 UTC 2012

Dick,

I saw your references to other posts, but not having seen them I had to go on what you had written, and I saw it in the context of the fact that we had 
mentioned efforts made by other companies to develop face recognition software.  However, I accept your point and am glad there is a better explanation 
than what I had concluded.  You make valuable contributions here and your work on drawing software is very important.

Best regards,

Steve Jacobson
