Journal ArticleDOI
Personal identification based on iris texture analysis
TL;DR: A bank of spatial filters, whose kernels are suitable for iris recognition, is used to capture local characteristics of the iris so as to produce discriminating texture features and results show that the proposed method has an encouraging performance.
Journal ArticleDOI
Efficient iris recognition by characterizing key local variations
TL;DR: The basic idea is that local sharp variation points, denoting the appearing or vanishing of an important image structure, are utilized to represent the characteristics of the iris.
Proceedings ArticleDOI
Iris recognition using circular symmetric filters
Li Ma,Yunhong Wang,Tieniu Tan +2 more
TL;DR: The method consists of three major components: image preprocessing, feature extraction and classifier design, which uses an efficient approach called nearest feature line (NFL) for iris matching.
Iris Recognition Based on Multichannel Gabor Filtering
Li Ma,Yunhong Wang,Tieniu Tan +2 more
TL;DR: A new approach for personal identification based on iris recognition is presented, which uses a bank of Gabor filters to capture both local and global iris characteristics to form a fixed length feature vector.
Journal ArticleDOI
Local intensity variation analysis for iris recognition
TL;DR: An attempt to reflect shape information of the iris by analyzing local intensity variations of an iris image by constructing a set of one-dimensional intensity signals that reflect to a large extent their various spatial modes and are used as distinguishing features.
