“...why use a machine that used OCR when you want a mirror image of the document a bit by bit copy. There was no need to determine what character is what. If it is a “6” or is an “8” ? You would not. You want a picture a photograph like image.”
NBC is not claiming that OCR recognized a “6” or an “8” as a number. NBC contends that the Xerox copier uses an international JPEG standard software called “Mixed Raster Compression” incorporating an algorithm called “image segmentation” to identify borders and shapes. If a shape is repeated closely, then the first one is copied rather then saving a second or subsequent shape that is only slightly different.
http://en.wikipedia.org/wiki/Mixed_raster_content
“Mixed raster content, or MRC, is a method for compressing images that contain both binary text and continuous-tone components, using image segmentation methods to improve the level of compression and the quality of the rendered image.[1] By separating the image into components with different levels of compressability, the most efficient and accurate compression algorithms for each type can be used.”
http://en.wikipedia.org/wiki/Segmentation_(image_processing)
“Compression based methods postulate that the optimal segmentation is the one that minimizes, over all possible segmentations, the coding length of the data.[5][6] The connection between these two concepts is that segmentation tries to find patterns in an image and any regularity in the image can be used to compress it.”
So when the compressed JPEG is opened in Preview on a Mac and then saved as a pdf file, instead of four similar lower case letter “e” images appearing in the LFBC, there is only one “e” repeated four times, IIRC. If you read the NBC blog there is a lot of explanation of this.
MRC as an explanation has been around since the LFBC PDF was first release.

The artifacts you see are a result of PDF compression...in this case a kind of Mixed raster compression alrogithm was used. You guys are silly...

Also when NBC talks about the JPEG, I believe the reference is to the green background layer. That layer is a JPEG and the other layers are bit maps.
The PDF was created on the Xerox by the Xerox. Then e-mailed to a user who opened it on a Mac in Preview.
But it sounds like he is saying that it is very temperamental. For instance, it might recognize two typewriter a’s as being close enough to just copy the first one where the 2nd one goes - but wouldn’t recognize 2 boxes with just a pixel or two off. And the German researcher found that it would substitute 8’s and 6’s. If an 8 is close enough to a 6 but a box with a pixel or two off isn’t close enough, something seems screwy to me.
Mr. K, you said at one point that these claims are baloney, noting that you have programmed imaging software. Do you have any insights as to how the compression could be insensitive enough to mistake an 8 for a 6 and yet not recognize every 6 as being the same?
Also, anybody with an engineering, architecture, or construction background, tell me the likelihood that 8’s and 6’s have been switched around on Xerox copies of blueprints for the past 9 years and nobody has noticed the problem in all that time.
Why would they scan it on the Xerox and not save it until it was on a Mac? They didn’t do that with the tax return NBC cites. Of course, that tax return is the only one that mentions Xerox WorkCentre. If the Xerox does all scans in landscape orientation, then wouldn’t the tax form be sideways unless it was first previewed, rotated, and then saved - yielding a PDF producer other than the Xerox?
I knew something was screwy with the WH long-form file when I tried C&P-ing it into a Word document and it showed the haloes. I wanted to test whether the same thing happened with other documents scanned and posted at whitehouse.gov but my computers are giving me trouble again.
Just so you know, Zullo has mentioned that the security background doesn’t match that used at the HDOH at the time, so his emphatic claim that the White House image is absolutely known to be a forgery is not just based on the artifacts and/or computer analyses.
There is no OCR table in the original file.
You can always have Adobe make a document searchable and thus create an OCR table. But the original document is not searchable, there is no text in the file.
Here is the text from the original AFTER it was processed to make it searchable via OCR.
As Red Steel indicates. This is all smoke and mirrors and it not even good smoke and mirrors.
There simply is no OCR table in the original file.
I still would like the explaination of why this ‘document’ (cough, cough) is the only one known to exist that combines the bend in the image on the left that shows a document that was photo-copied or mimiographed while it was still in a bound volume (like the 1960s Nordyke certified copies) and is printed on modern security paper like so many Hawaii BC images. No other Hawaii LFBC shows this ‘left bend’ that comes from images to make certified copies in the 1960s before the documents were scanned (FLAT!) into digital library. This was likely an optical library using CDs or DVDs for WORM storage.
So again this is only document to exhibit this characteristic in the entire world.
Odd.
