In recent years, advertisers and magazine editors have been widely
criticized for taking digital photo retouching to an extreme. Impossibly
thin, tall, and wrinkle- and blemish-free models are routinely
splashed onto billboards, advertisements, and magazine covers.
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. |
