But, after a looking around I found a neat tool, that which provides a nice analysis of photos. After that, a little bit of intuition and you can identify what part of the photos were faked out.
Here’s how it works.
- Upload your images to imgur or any other image hosting service.
- Submit the link of the image to http://errorlevelanalysis.com/
- Next you will see a heat map of the image that highlights areas with error.
In the heat map, you can look see that the area that was edited looks a bit out of place. It’s not entirely intuitive, but it’s a neat starting point.
Here’s a great read about the tool: http://www.techlikes.com/2010/09/23/software-tool-to-detect-fake-images.html – In the example, notice that there’s a mistake – the fake photo error level analysis is swapped with the real one, compared to the fake and real photos.
Disclaimer: Don’t go making accusations based on what you THINK is fake based on this tool, unless you are an expert.
