“If the Xerox machine is substituting exact replicas every time a certain “blob” (such as a box) appears, then that should happen with every box, every letter, etc.”
The algorithm does not appear to be very precise, but just the fact that there is such an algorithm and the effects of the algorithm are NOT evident in the AP scan, but ARE evident in the WH pdf seems to support that this is what happened.
A criminal case “beyond a reasonable doubt” is being put forward by Zullo and he is asking congressmen to sign on, so these claims by NBC must be either refuted or affirmed, preferably by independent investigators who are not already in the Obot or “birther” camp.
This should not be hard to do since NBC has finally released his/her own pdf with the claimed replications and a step-by-step hardware/software workflow that can be readily replicated, I would think.
Zullo has repeatedly asked for anyone to step forward if they believe they can replicate the WH pdf and here is such a claim.
I am not an expert on this, but would Xerox be using a grayscale (8 bit) to black and white (2-bit) conversion for scans of these text images? Grayscale, of course, provides more information for further processing. You would have to have multiple scans of 8-bit to 2-bit of the same test image and then examine the results under a magnifying glass.
What artifacts do you mean, that aren’t on the AP scan? By AP scan you mean the Applewhite image?
