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.
