Is an image in its original stage or has it been manipulated in an image editor? Image editors have become that good that it is virtually impossible to tell by looking at the image in question unless it contains flying elephants or similar unrealistic footage. But what about that ufo image that your friend send you, the images from the girl that you met on a dating site or the images that have been published on digital camera manufacturers site?
JPEG Snoop is a tiny portable software program that can analyze the ins and outs of any digital image that the user loads into it. Supported are various image formats including jpg, pdf, crw, dng, cr2, new, orf, pef, thm and even mov and avi.
The software program will display many information about the image in a text editor like interface. The interesting part for users who want to identify if an image has been manipulated is at the end. The program will compare the compression characteristics of the image and assign an assessment class to it in the end.
Four assessment classes are defined:
- Class 1 – Image is processed/edited
- Class 2 – Image has high probability of being processed/edited
- Class 3 – Image has high probability of being original — NOTE: Please see description below!
- Class 4 – Uncertain if processed or original
We mentioned earlier that JPEG Snoop is able to process video formats as well. It can analyze a single frame of a video that is loaded into the software. The program might be interesting for users who regularly need to analyze the ins and outs of images.
