Photoshopped Iranian Missile Launch

Some time ago I wrote about my implementation of an algorithm for detecting copy/paste for doctoring photographs. Today the New York Times reports that a photograph of an Iranian missile launch appears to have been doctored.

Here's the picture:

I ran it through my code and it quickly shows up large chunks of smoke that appear to have been displaced:

Tweaking the knobs on the algorithm would probably show more smoke copying, but I don't have the free time.

While we wait for them the finish, MooPig coveted Awards Editors would like to give John Graham-Cummings its scoop of the month award: Fraternal Order of the Penguins of Irony patch shown at the top of the page. Congratulations, nice over and above work on our order of chaos.

Well, no doubt at all their photo was chopped. But for an authentic pic of an actual Iranian launch I offer this one...

John Graham-Cumming, thank you. I have developed a copy-move tool which can be run at Windows.

I think young people nowdays must work on keeping their own culture by preserving national values.
This could be achieved by keeping these values in a museum.
The Politechnics University Museum site was realized by a few students beeing published temporarily here:
It represents a science museum in where we can find varius hystorical technical models.
For improovments of the site wich is just a scale model you can write us a message on the
Contact Form.
Thanks for your support.
