This study introduces a novel footprint recognition method. Normalizing footprint data significantly improves personal identification accuracy from 30.45% to 85.00%.

Area of Science:

  • Biometrics
  • Computer Vision
  • Forensic Science

Background:

  • Personal recognition is crucial in security and forensics.
  • Existing biometric methods have limitations.
  • Footprint analysis offers a unique biometric modality.

Purpose of the Study:

  • To develop and evaluate a novel personal recognition method using footprint biometrics.
  • To enhance the accuracy and robustness of footprint-based identification.
  • To investigate the effectiveness of geometric information and normalization techniques.

Main Methods:

  • A new personal recognition method based on footprint analysis was proposed.
  • Raw footprint images were normalized for direction and position to improve matching.
  • Euclidean distance and geometric information (directional, positional) were utilized.
