Abstract :
The paper presents a novel approach, mainly based on fractal dimensions, for recognizing the iris of a human eye. The proposed system consists mainly of four modules: iris image acquisition; iris image preprocessing; iris feature extraction; iris pattern recognition. Two methods for extracting the iris features based on the fractal dimension are proposed. Recognition performances of 91.18% in accepting authentics and 100% in rejecting fakers are obtained.
