WebDaugmanアルゴリズムは高い割合の精度を提供する虹彩認識技術の一つである。 Raspberry PiのDaugmanアルゴリズムを用いた虹彩認識を行う装置を開発した。 … Webperformed by using the Daugman’s algorithm which is an integro-differential operator capable of separating or segmenting out regular shapes. The Daugman’s algorithm also has a noise smoothening capability. Both these attributes make the Daugman’s algorithm a preferred choice for iris localization.

WebAug 24, 2006 · Abstract: In this paper, we presented an iris recognition algorithm based on modified Log-Gabor filters. The algorithm is similar as the method proposed by Daugman in general procedure while modified Log-Gabor filters are adopted to extract the iris phase information instead of complex Gabor filters used in Daugman's method. WebDaugman proposed an integro-differential operator to find both the pupil and the iris contour. Daugman’s method is claimed to be the most efficient one. This paper proposes an implementation for Daugman's algorithm, which was found incompatible with visible light illuminated images. Then this paper proposes new algorithm for solving this ...
