Thing is, these enlargements are indeed pretty much worthless. Apart from the fact that they clearly *have* used an interpolation technique, which adds in pixels on a rough-guess basis, the image is almost certainly already compromised by the aforementioned issues like compression and sharpening/contrast enhancements, let alone being over- or digital-zoomed, out-of-focus and motion blurred...
Such enlargements are, 'forensically', worse than useless. But (oft times) they can be great for folks who want to find 'detail' they can somehow add to their tantalisation.. And of course if the 'researcher' can then add on a bit of post processing, like additional sharpening, posterising, edge filtration ad infinitum, they can adjust the sliders to get pretty much anything they want...
Tell me if you agree with the findings.
