Fingerprint image restoration algorithm using a fourth-order partial differential equation |
Contents |
In this presentation, we consider a fingerprint image restoration algorithm using a fourth-order partial differential equation which is the nonlocal Cahn–Hilliard (CH) equation. The equation was originally proposed for modeling the microphase separation of diblock copolymers. The main idea is to use information from neighboring data of the damaged fingerprint. Numerical tests show the superior performance of the proposed method. (MATLAB 실습을 할 예정입니다. 훼손된 지문 복원 프로그램 MATLAB 코드는 세미나 당일 줌을 통해서 드리겠습니다. MATLAB을 준비하시면 도움이 많이 됩니다) |
