METHOD AND APPARATUS WITH IMAGE PREPROCESSING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17862568 titled 'METHOD AND APPARATUS WITH IMAGE PREPROCESSING

Simplified Explanation

The abstract describes a method for preprocessing fingerprint images using a processor. Here is a simplified explanation of the abstract:

  • The method transforms a fingerprint image into the frequency domain.
  • It suppresses a low-frequency region that corresponds to a noise component in the fingerprint image.
  • The method then restores the frequency domain, resulting in an image where the low-frequency region is suppressed.

Potential Applications:

  • Biometric authentication systems: The technology can be used in fingerprint recognition systems to enhance the accuracy and reliability of fingerprint matching.
  • Forensic analysis: The method can aid in the analysis of fingerprint evidence by improving the clarity and quality of fingerprint images.

Problems Solved:

  • Noise reduction: The method effectively suppresses low-frequency noise in fingerprint images, resulting in cleaner and more accurate representations of fingerprints.
  • Image enhancement: By restoring the frequency domain, the method improves the overall quality and clarity of fingerprint images, making them easier to analyze and match.

Benefits:

  • Improved accuracy: By reducing noise and enhancing image quality, the method can lead to more accurate fingerprint matching, improving the reliability of biometric authentication systems.
  • Enhanced forensic analysis: The technology can assist forensic experts in analyzing fingerprint evidence by providing clearer and more detailed images, potentially aiding in criminal investigations.


Original Abstract Submitted

A processor-implemented method with image preprocessing includes: transforming a fingerprint image into a frequency domain; suppressing a low-frequency region corresponding to a first noise component of the fingerprint image in the frequency domain; and restoring the frequency domain, in which the low-frequency region is suppressed, as an image.
