Abstract

In this paper a new algorithm is introduced to enhance the fingerprint image effectively using fuzzy logic. Our approach is not constrained to a particular image size and scale. It rather handle different conditions of noise and image scale. Ridges are thinned while the image is enhanced along the same orientation as the ridges. The problem of false minutia can be also resolved.

본 논문에서는 퍼지 논리를 사용하여 지문 영상에 적용할 수 있는 효과적이 세선화 알고리즘을 제시한다. 제시하는 알고리즘은 잡영이 많이 포함된 영상이나 서로 다른 크기를 가진 영상도 효과적으로 향상시킬 수 있다. 문헌에 나타나는 대부분의 지문 영상 필터들은 특정 크기, 혹은 특정배율의 지문 영상을 대상으로 설계되었으나 본 논문이 제시하는 알고리즘은 영상 크기 변화에 따른 마스크의 크기와 계수 값의 재설계가 필요 없다.
