Darthmouth College researchers used 3D computer models to proof the authenticity of famous backyard photo of Lee Harvey Oswald.
The legendary backyard photo of Lee Harvey Oswald is real, says a new Dartmouth study.
The photo shows Lee Harvey Oswald holding the same type of rifle used in the President John F. Kennedy assassination.
The new research eradicates the claims that the photo was faked. Oswald's pose is supposed to be physically implausible.
Using new digital image forensics techniques and a 3D model of Lee Harvey Oswald Oswald developed by the Dartmouth researchers proof that the photo is real.
"Our detailed analysis of Oswald's pose, the lighting and shadows and the rifle in his hands refutes the argument of photo tampering," says senior author Hany Farid, a professor of computer science and a pioneering researcher in digital forensics whose team develops mathematical and computational techniques to detect tampering in photos, videos, audios and documents.
Lee Harvey Oswald was killed before his trial. There was never a full account of the assassination from him. This is to date fueling conspiracy theories.
The theories are based on inconsistencies in the events of Nov. 22, 1963. Additionally the evidence collected against Oswald has been scrutinized.
One of the evidence is the photograph of Oswald in his backyard.
He holsters a pistol and is holding a rifle in one hand and Marxist newspapers in the other.
At the time of his arrest, Oswald claimed the photo was fake.
The Warren Commission and the House Select Committee on Assassinations concluded claims of photo tampering were unwarranted.
Also, Farid's studies in 2009 and 2010 refuted the claim that the lighting and shadows are inconsistent, but these studies did not address claims that Oswald's pose is physically implausible.
In the new study, Farid and his team conducted a 3-D stability analysis to determine if this claim is warranted.
"Our analysis refutes purported evidence of manipulation in the Oswald photo, but more generally we believe that the type of detailed 3-D modeling performed here can be a powerful forensic tool in reasoning about the physical plausibility of an image," Farid says. "With a simple adjustment to the height and weight, the 3-D human model that we created can be used to forensically analyze the pose, stability and shadows in any image of people."
