Analyzing bite marks on skin is challenging. A new image perception technology enhances detail visualization, potentially improving bite mark analysis and comparison with dental records for forensic identification.

Area of Science:

  • Forensic Odontology
  • Image Analysis
  • Biometrics

Background:

  • Bite mark analysis compares dental features from evidence to suspects.
  • The uniqueness of human dentition is a key assumption, but definitive proof is difficult.
  • Detailed analysis requires high-quality bite mark and dental impression data.

Purpose of the Study:

  • To introduce a novel method for bite mark analysis.
  • To explore the application of image perception technology in forensic odontology.
  • To enhance the visualization and comparison of bite mark evidence.

Main Methods:

  • Utilizing image perception technology for bite mark analysis.
  • Applying artificial coloring to areas of equal intensity.
  • Transforming 2-D bite mark images into pseudo-3-D surface representations.

Main Results:

  • The image perception technology allows for enhanced visualization of bite mark details.
  • The method facilitates the depiction of 2-D images as pseudo-3-D objects.
  • Potentially reveals details not discernible through conventional methods.

Conclusions:

  • Image perception technology offers a promising advancement in bite mark analysis.
  • This technique may improve the accuracy and detail in comparing bite marks to dentition.
  • Further research can validate its effectiveness in forensic identification.
