Photoshopped or Not? A Tool to Tell
A proposed software tool is intended to address concerns about the prevalence of highly idealized and digitally edited images in advertising and fashion magazines. The New York Times reports.
... Feminist legislators in France, Britain and Norway say, and they want digitally altered photos to be labeled. In June, the American Medical Association adopted a policy on body image and advertising that urged advertisers and others to “discourage the altering of photographs in a manner that could promote unrealistic expectations of appropriate body image.”
Dr. Hany Farid said he became intrigued by the problem after reading about the photo-labeling proposals in Europe. Categorizing photos as either altered or not altered seemed too blunt an approach, he said.
Dr. Farid and Eric Kee, a Ph.D. student in computer science at Dartmouth, are proposing a software tool for measuring how much fashion and beauty photos have been altered, a 1-to-5 scale that distinguishes the infinitesimal from the fantastic.
Their research is being published this week in a scholarly journal, The Proceedings of the National Academy of Sciences.
Introduction to their paper:
The ubiquity of these unrealistic and highly idealized images has been linked to eating disorders and body image dissatisfaction in men, women, and children. In response, several countries have considered legislating the labeling of retouched photos.
We describe a quantitative and perceptually meaningful metric of photo retouching. Photographs are rated on the degree to which they have been digitally altered by explicitly modeling and estimating geometric and photometric changes. This metric correlates well with perceptual judgments of photo retouching and can be used to objectively judge by how much a retouched photo has strayed from reality
