This study compared two computer imaging programs for assessing facial appearance. The morphing program proved more user-friendly for evaluating subjective facial profile acceptability.

Area of Science:

  • Computer imaging
  • Facial soft-tissue profile analysis
  • Subjective perception

Background:

  • Understanding the physical basis of subjective facial appearance is crucial in fields like orthodontics and plastic surgery.
  • Previous methods for assessing facial aesthetics lacked objective, quantifiable measures.

Purpose of the Study:

  • To compare two novel computer-imaging programs for evaluating subjective judgments of facial appearance.
  • To establish the physical basis of aesthetic preferences in facial soft-tissue profiles.
  • To determine the reliability and validity of digital morphing versus animation techniques in facial analysis.

Main Methods:

  • Two computer-imaging programs, 'animated' distortions and 'morphed' transitions, were used to present 5 facial soft-tissue profile features.

  • Images were digitally altered from 16 discrete distortions or morphed between extremes.
  • 12 volunteer judges rated image acceptability and pleasingness using mouse-based interaction.

    • Main Results:

    • Both programs demonstrated high correlations in measuring the midpoint of acceptability.
    • The digital morphing program was found to be more user-friendly than the animation method.
    • Both methods provide reliable and valid assessments of facial morphology acceptability.

    Conclusions:

    • Novel computer-imaging programs can reliably quantify subjective facial appearance judgments.
    • Digital morphing offers a more user-friendly approach for assessing facial profile aesthetics compared to animation.
    • These tools can aid in understanding and predicting patient satisfaction with proposed facial changes.
