[Tell HN]: I built a web app for image forensic analysis. Thoughts?
I made something cool, and I just wanted to share it.
There was an article submitted here last month, about forensic analysis of a recent Victoria's Secret photo (Discussion here: http://news.ycombinator.com/item?id=1017726)
It raised my interest, and I thought it was a great article. HN User slig made a quite comment about how some parts of it would be pretty easy to implement as a 'web app'. Turns out he was right. I read up on the theory in the linked research paper, and here is the result of a few days work:

Any thoughts or suggestions, I'd love to hear them.

- joshu 17y agoI like it, but would like to see something more general. Copy-move detection would be neat: http://www.lemonodor.com/archives/2008/02/protecting_journalistic_integrity_algorithmically.html http://www.lemonodor.com/archives/2008/02/protecting_journal...
- pgr 17y agoOh, cool. I'd seen that before but I was unaware that the source code had been posted. Thank you for the link.
- olalonde 17y agoCool project ! Care to open source your error level analysis implementation ? I'm curious of how complex it is.
- pgr 17y agoSure, here is a link: http://errorlevelanalysis.com/source/ http://errorlevelanalysis.com/source/
- pbhjpbhj 17y agoIf the theory is correct, on a cursory glance I'm not convinced, then could you not do a quick analysis to give a numeric likelihood of the image having been tampered with?
