Four years ago Dartmouth prof Hany Farid presented alleged "proof" the Oswald backyard rifle photos were "real". Google the name “Hany Farid” and you will bring up about 5,000 pages on the Dartmouth computer software scientist – from almost as many news sources – all parroting that he has “proven the Oswald backyard rifle photo is genuine." (One begins to wonder from this if the CIA's "Operation Mockingbird" is still going on.). For those who may not know, this is the infamous photo taken in the Oswalds’ backyard on Neeley Street in Dallas, sometime in March, 1963 (as documented from FBI files by Mark North in his ‘Act of Treason’) .
I did my own analysis of the backyard photos, based on the reasonable assumption that any transformation from specular dots on silver iodide based (1963) photo emulsions will undergo some drift over time in rectangular coordinates such that this time-affected diffusion needs to be examined using fractional calculus equations of the form : d’(x) = wH×(d(x)bH) and d’(y) = wV×(d(y)bV).
An illustration of applying the parameters d'(x) and d'(y) to respective pixel sub-frames is shown in the accompanying graphic. These measure fractal deviations in pixel density from one Oswald photo to the other (there were 4 in all) and from which the weighted error in the conceptual space may be computed.
I give some of the results below for the diffusion factors, Dt(xb) and Dt(yb) done using a Mathcad 14 software program. This is based on comparison of two photos (A and B) with the same regions selected as “prototypes” and the mapping done one to one, e.g. from points of dx1 to dx1’ and dy1 to dy1’. We start out with initial values: y = dy1 = 2.7 mm, and x = dx1 = 3.4 mm.
"Yet, impossibly, while one body is bigger - the heads match perfectly."
Again, this can be explained using the same "spliced out head" re-incorporated into each image..
It is incredible Farid has not performed this simple test, but then that would mean divorcing himself from his computer- which he obviously believes to be the next thing to an Oracle. In the above context, I am convinced that Farid’s preoccupation with statistical disparities or deviations in pixel density is only useful provided he knows the full and complete history of the object-film-photographic emulsion he is investigating. In particular, what criteria has he to implicitly trust the source photo? As my middle brother, a former photographic specialist with the Air Force in the 1960s also pointed out to me
“First of all he'd have to have had the original photo of Oswald, not a copy, which I doubt very much he had, since the Feds confiscated it and only allowed reprints. Secondly, in those old photos there were no pixels to measure since all photos of that period were taken with film type cameras and no pixels were on them to measure. The photos looked the same as a painted picture, smooth and even ”
To add to what he said, I do admit Farid could have generated pixels from the old photos (to enable and facilitate computer processing), but also - as I pointed out- he'd have to use fractional calculus at all inter-comparison points between all the relevant photos to be assured of a faithful reproduction or representation following any transformations of media. Since it isn't at all clear he did this, then basically he revived computer formats of the old photos, which appear to have already been tampered with, and reproduced the same errors. Farid actually re-discovered the tampering, but was too blinded by his computer processing tools to see it. To make a long story short, and skip to the chase, the differential fractional calculus transformations disclose that the V-shaped shadow under Oswald's nose is essentially identical in all photos, despite the fact the photos were taken at different times.
