ELECTRONIC APPARATUS AND METHOD OF PROCESSING FINGERPRINT IMAGE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18166826 titled 'ELECTRONIC APPARATUS AND METHOD OF PROCESSING FINGERPRINT IMAGE

Simplified Explanation

The patent application describes a method for processing a fingerprint image in an electronic device. Here is a simplified explanation of the abstract:

  • The method starts by obtaining an original fingerprint image by sensing a user's fingerprint.
  • It then estimates the spatial change trend of the original contrast values in the fingerprint image.
  • Based on this estimated trend, a reference contrast map is generated.
  • The contrast distribution of the original fingerprint image is then normalized using the reference contrast map.
  • The result is a normalization fingerprint image with a normalized contrast distribution.

Potential Applications:

  • Biometric authentication systems: The technology can be used in fingerprint recognition systems to improve the accuracy and reliability of fingerprint matching.
  • Forensic analysis: The method can aid in analyzing and comparing fingerprints in forensic investigations.

Problems Solved:

  • Inaccurate fingerprint recognition: The method addresses the problem of variations in contrast within fingerprint images, which can affect the accuracy of fingerprint recognition systems.
  • Inconsistent fingerprint quality: By normalizing the contrast distribution, the method helps to overcome issues caused by poor image quality or different sensing conditions.

Benefits:

  • Improved accuracy: The normalization process enhances the contrast distribution, leading to more accurate fingerprint recognition results.
  • Robustness: The method can handle variations in contrast caused by different sensing conditions or image quality, making it more robust in different scenarios.
  • Efficiency: By normalizing the contrast distribution, the method can improve the efficiency of fingerprint recognition systems by reducing false positives and false negatives.


Original Abstract Submitted

A method of processing a fingerprint image in an electronic apparatus includes: obtaining an original fingerprint image by sensing a fingerprint of a user; estimating a spatial change trend of original contrast values in the original fingerprint image; generating a reference contrast map based on the estimated spatial change trend; normalizing a contrast distribution of the original fingerprint image based on the reference contrast map, and generating a normalization fingerprint image having a normalized contrast distribution.
