Researchers at Dartmouth College have developed a metric to apply to
altered images to address how much Photoshopping a
picture has undergone, in an effort to provide more truth in
advertising and prevent unhealthy body image issues.
Farid and Eric Kee, a Ph.D student in computer science at Dartmouth,
published their research this week in the journal National Academy of Sciences.
The
tool would work on a rating scale of one to five. Farid and Kee created a base
metric by analyzing and statistically measuring results from various
before-and-after photos. They then correlated these findings with a study group
that was asked to rank the amount of photo alteration on a scale of one (very
similar) to five (very different). This numbered metric could then be
algorithmically applied to photos of, say, celebrities and models to reveal
just how much photo-manipulation took place.
