Researchers developed a digital algorithm for lip print analysis, finding it works best on uniform backgrounds. The study did not find a link between lip groove patterns and sex.

Area of Science:

  • Forensic Science
  • Biometrics
  • Digital Image Processing

Background:

  • Lip prints offer unique identification markers.
  • Digital analysis of lip prints can enhance forensic investigations.
  • Standardized methods for lip print analysis are lacking.

Purpose of the Study:

  • To develop and evaluate an algorithm for lip print visualization and digital analysis.
  • To assess the performance of the algorithm on various surfaces.
  • To investigate the potential of lip prints for sex classification.

Main Methods:

  • A batch image processing algorithm was created to identify and extract lip groove information.
  • Lip prints were analyzed on different supports (paper, glass slab, glass, compact discs).

  • Superimposition techniques were used for digital analysis.

    • Main Results:

    • The algorithm performed better on lip prints with uniform backgrounds.
    • Paper and glass slabs yielded more accurate identifications compared to glass and compact discs.
    • No significant difference was found in the middle lower lip area across supports.
    • No association was found between lip groove types and sex.

    Conclusions:

    • Digital methods are crucial for advancing lip print analysis.
    • The developed algorithm shows potential but requires optimization for varied backgrounds.
    • Lip groove patterns (Type III and I) are common in both sexes, limiting their use in sex determination.
