Example of Point-of-Sale Storefront Scenes Edited to Include Either a Flavored (Left) or Unflavored (Right) E-Cigarette Product Advertisement

Note.

Pairs of advertisements were first selected to qualitatively match on visual features (eg, overall color, design, white space and location of products). Quantitative analysis of image saliency as well as luminance and contrast indicated that flavored and unflavored e-cigarette advertisements were well-matched on these features. All other aspects of the scene were untouched.
