This study introduces a computational method using wavelet statistics to authenticate art. The technique analyzes digital scans to confirm artist attribution and identify multiple contributors to artworks.

Area of Science:

  • Computational Art Authentication
  • Digital Image Analysis
  • Statistical Pattern Recognition

Background:

  • Art authentication relies on expert analysis, which can be subjective.
  • Digital technologies offer new possibilities for objective art analysis.
  • High-resolution scans capture intricate details crucial for authentication.

Purpose of the Study:

  • To develop and validate a computational technique for authenticating paintings and drawings.
  • To create a statistical model of an artist's style from digital scans.
  • To compare the computational results with expert opinions in art authentication.

Main Methods:

  • Utilizing high-resolution digital scans of artworks.
  • Building statistical models based on first- and higher-order wavelet statistics.

  • Comparing statistical models of new works against authenticated artist models.

    • Main Results:

    • Preliminary results confirmed expert authentications for 13 drawings attributed to Pieter Bruegel the Elder.
    • The technique successfully identified multiple artists contributing to a painting attributed to Pietro Perugino.
    • Computational analysis aligned with established expert opinions in both case studies.

    Conclusions:

    • Wavelet statistics provide a robust computational method for art authentication.
    • This technique can objectively support or challenge existing art attributions.
    • The approach has potential for broader application in art history and conservation.
