While I am working on Part IV in the series on the LFBC and the Xerox WorkCentre’s I thought I would take time to follow-up on the halo creation in PDF’s that occurs when documents with color backgrounds and dark text are scanned on a WorkCentre with MRC compression.
I created a very simple document. I printed a text document from MS Word on a sheet of green security paper and then scanned it on the WorkCentre 7535 to email as a PDF using all the default settings (300 dpi, color, Edge Erase set to 0.1”).
The result was just as I expected. When the document is opened in Illustrator it is rotated to landscape mode. I have found this to be consistently true. There are technical reasons for that happening that will be covered later. It always happens with Illustrator. Other programs render the Xerox PDF’s correctly. It was true of the PDF I discussed in the previous article but for clarity I rotated the overall PDF and the layers to portrait for clarity.
While I did this just for fun the document turned out to be very useful.Here is the PDf version from the Xerox WorkCentre 7535: Zebest on Green SP
Let’s take a look at my “Zebest” test document:
This is a cell phone photo so there is a little glare from the flash. You can see that the letters are nice and crisp and without halos.
I scanned the document in the trusty WorkCentre 7435 to see what would happen. Would Mara’s own words create halos?
Here is the full scan: (Notice the border added by the Xerox Edge Erase feature)
This is a high resolution PNG file exported from Illustrator and rotated. Here is part of the text blown up to show the halos:
Let’s zoom in even more to show the halos:
Yep, there they are.
What about the layers? We should expect that the WorkCentre 7535 and MRC/JBIG compression would create the familiar background JPG and multiple foreground masks. Indeed that is what we see. In the case of this simple document there are three layers. One is the familiar background JPG with the green security background. Also notice the white “holes” where the test was extracted to form the monochrome masks.
Here are the layers: I left them in landscape as they appear in Illustrator:
Background:
So do you still think the green background was added in the way Mara Zebest claimed it was in her affidavit? Remember what Ms. Zebest said?
In summation, the security paper background layer was added as the last step to create the illusion of an image in which text was imprinted on security paper. However, the text had in factbeen placed and arranged on a solid white background. This last application gives a created image the false appearance of being an official document.

Here are the two monochrome text layers exported from Illustrator:
So as you can see even in such a simple document as this the Xerox separated the text out somewhat randomly into two layers.
I wish to give a special shout out to Mara Zebest for her contribution to this article. Also thanks to gsgs for asking questions. There is nothing wrong with asking questions as long as you are willing to listen to the answers.
You also have the letters that are pixel-for-pixel duplicates and in certain letter combinations (tt and ff) the software filed in the small space between with black pixels.
OMG you are correct. Look at all the e’s that are identical. That Zebest is a crafty forger.
thanks.
I think the halos are also in the original first pic. as some isolated lighter pixels
in the areas where the 2nd pic. shows the big halos (best seen when enhancing
colors, Illustrator should have such a feature ?!).
So the MRC somehow enhances the halo, maybe smoothening the 8*8 blocks
but choosing not the average color , but maybe the maximum (lightest )
This is speculation – I didn’t yet test the pictures very much.
Also remember, Kevin’s theory that the halos are just created by chromatic aberration
and then maybe somehow enhanced.
Maybe we can figure it out before the last nail is posted …

I think we should figure out the method, how the pixels were chosen that
replace the mounted foreground before.
The algo of the program.
The ultimative,exact plan of the forger 😉
It shouldn’t be so complicated (IMO)
That would enable us to rewrite the program, to compute each pixel
The halo thing looks like an unpleasant bug in the Xerox software.
Maybe there was an update to replace that program.
with 16×16 grid
so, can you scan to bmp or png or gif or tif ?
instead of lossy jpg inside pdf .
Then we can calculate the exact pixels and detect the MRC algorithm
The 7535 can scan to TIFF. I will scan the original when I get a chance.
I believe you would agree that the WorkCentre was the source of the halos on the LFBC PDF then.
“Also remember, Kevin’s theory that the halos are just created by chromatic aberration”
Once again: Does not apply to scanners.
what document was the WH-pdf scanned from ? I think that one did have
some halos and/or chromatic aberration already.
Do we have a direct scan without intermediate camera-pic from
the 2011/04/27 press-laser-printout ?
(btw. no reply from OD yet)
The WH pdf was scanned directly from the birth certificate, which itself was copied directly from the original bound birth record (likely on a Xerox WorkCentre Pro 265) – this document would not have halos. I believe the press release print-out was a b&w (1-bit, not greyscale) scan of the birth certificate made at the same time the other b&w scans of the correspondence were made, and these were subsequently printed out for the presser. The correspondence documents are available on the WH site, and do not have the chromatic aberration or other halos seen in the photographs of the press release.
thanks. I never read this before, afair. How do you know ?
“correspondence documents” is this 4-page pdf ?

pity that we don’t have one of those press-laser-copies nor a good scan of one
I think the WH should sell them to anyone
It is based on a timeline I reconstructed in the last few months. Circumstantial evidence, but here it is:
1. The WH correspondence has a time-stamp almost identical to the WH LFBC, with a Preview creator..
2. The timestamp is formatted for the universal time zone, rather than a local one.
3. This equates to a ~8:00 am local scan of the documents, rather than noon, before the presser.
4. In addition to taking pictures of the individual pages a few minutes after the presser, (and on each photo, you can see the next page bleeding through), Applewhite uploaded a jpeg of the LFBC with a green basketweave pattern with the same timestamp as the other photos (let’s call this the AP green).
5. Upon close inspection of the AP green, it does not have the chromatic aberration that can be seen in the other photos. It also has a number of features seen in the WH LFBC, but not the AP blue.
6. It is my conclusion that the AP green is the WH LFBC that has been flattened, cropped, and saved as a JPEG, rather than an actual photograph.
7. If this is true, then the timestamp on the WH LFBC must be for universal time, not local, meaning it and the correspondence were scanned prior to the presser.
8. This leads to two possibilities:
.8a. The documents were scanned, and then the scans were printed out.
.8b. The documents were scanned, and then photocopied while on the scanner.
9. Upon further consideration, I now think 8b is more likely (although there have been reports from unreliable sources that a white LFBC was originally shown on the WH site, but that could be a reference to the copy of the Snopes short form image that is there now). This could be tested by examining the photographs of the press release taken by Applewhite, still available for purchase on APImages. NBC linked to those pictures last summer.
thanks. How can I get AP green ?
Has someone asked Applewhite ?
Shall I send email to him

presumably I need a wordpress account
gsgs, you do not need a wordpress account to post. I just noticed you had contributed. The first posting is moderated. You should be fine now.
NBC,
I think what GSGS is talking about is this line in your article:
MSNBC TV has the best AP JPEG DCS103 available
When you click on the link “available” you get a message “403 Access Denied” “his File requires authorization”
please scan this one to TIFF : http://magictour.free.fr/biwhgs3.7z
Or maybe the posse can do it for you – cooperate with them
instead of “driving nails in the coffin”
we need the tif(f), but also the background .ppm that extracts from the pdf
and shows the pixels that are behind the mounted black text
(although unfortunately only after being compressed with lossy .jpg)
Why? Their requirements to allow RC to work with them are just unreasonable… And they are not really interested in pursuing the facts. Do you really think otherwise??
I always cooperate with pathetic liars who try to claim I am a criminal. Or not.
yes, you can always cooperate on some issues with people you don’t like.
I cooperate with people who call me a f**king idiot and think they are wayyyyyyy
superior since they use long lines.
I have emailed copies of the scans to Mike Zullo. That is all I intend to do. He can read my blog and NBC’s blog. Everything they need is available.
The posse continues to be an embarrassment to law enforcement.
but they are working on the same project as we.
It’s their turn. Let them produce some pictures and Xerox scans
that we can analyze.
They are not working on the same project any longer, I am sure. The Xerox workflow embarrassed them and now they are looking for something ‘bigger’. Their in-actions speak louder than words.
GSGS
The CCP has the birth certificate they created from their first testing in 2012, they have access to a Xerox WorkCentre and they have NBC’s, RC’s and Kevin’s methodology. What’s stopping them?
the posse can’t just ignore this

that these 3 guys have the answer to one of the biggest
[I couldn’t understand} presidency in the nation’s history
…they don’t…. what we have ….
Oh, they will ignore this.. By moving on towards bigger and greater things and ignoring the xerox workflow findings.
Are you really believing that they are interested in the facts?
“Xerox is out of the window”
so they have done some analysis and they have some results.
And it’s a major subject. I assume they will address it somehow.
What these ‘3 guys’ have is an explanation for most of the artifacts that the ‘clown posse’ had insisted to be 100% evidence of a forgery.
If they had done their homework rather than ignore the evidence, and followed where John Woodman’s research was leading then they would not be in a situation of great embarrassment. But rather than accept their errors, they blame the messengers…
Pathetic… They never earned any respect and their continued shenanigans continue to expose their political motivations.
And worse, they cannot admit to being wrong… They’d rather see an innocent person accused…
yada,yada,yada
you keep saying this, everyone knows by now.
One would assume so, but somehow, they have shown no sign of such…
Somehow, sometime, somewhere… But not in the near future…
Let the clowning continue
we know, they usually communicate by press conferences,
not by website or forum posts as we do.
This is presumably to get bigger attention by the newspapers.
So they keep things secret until they can do the press conference.
This “need” for secrecy was especially pointed out in the recent radio-interview.
So, I think we can expect some press-conference in the next months.
This should involve the new “universe shattering” things, but also the
Xerox thing – both were mentioned by Zullo in the radio interview.
I mean, if they would keep it secret forever, how could it be
“universe shattering”, however they might define that term ?
The promissory note will keep the faithful from asking questions.
I’d suggest that we convert this series of
posts into a scientific paper
and publish it at arXiv.org (or such)
Title could be:
misinterpretation of “artifacts” in the electronic image
of Obama’s birth certificate
—————————————————————–
2 arxiv-hits for halo in Computer Vision and
Pattern Recognition (cs.CV)
1.) Dense Scattering Layer Removal
2.) Sparse Norm Filtering
———————————————-
I also noticed this unfortunate desire
for secrecy in scientific papers,so
it’s not just the posse.
Researchers are afraid that others might
be publishing something on the issue
before they [researchers] can publish
their paper in a peer-reviewed journal.
This publishing is then somehow considered
final then, no subsequent discussion
is wanted.
In this case the posse is afraid that
their findings are debunked before
they can present them to the press -;)
RC, please remove the email address above and replace it with “gsgs”
it’s common strategy in blogs to not display email addresses
because of spambots. It happened when I replied by email-reply to the
email notification from wordpress
Done.
I finally played around with “unsharp mask” after I read about it in Vogt’s affidavit.
And yes, it creates and enhances halos ! Not the big halos as in LIVE , this was probably
enhanced by the MRC, but MRC needs a halo to start with and I think this might have been
created with unsharp mask. I make a picture at fogbow
