Retina identification based on the pattern of blood vessels using fuzzy logic

Wafa Barkhoda, Fardin Akhlaqian, Mehran Deljavan Amiri, Mohammad Sadeq Nouroozzadeh
2011 EURASIP Journal on Advances in Signal Processing  
This article proposed a novel human identification method based on retinal images. The proposed system composed of two main parts, feature extraction component and decision-making component.  ...  In addition to high accuracy rate, rotation invariance and low computational overhead are other advantages of the proposed systems that make it ideal for real-time systems.  ...  The procedure is as follows: first we partition the image based on type of the partitioning and then we let number of sketch pixels within each section as feature value of that segment.  ...

Retinal Identification Based on an Improved Circular Gabor Filter and Scale Invariant Feature Transform

Xianjing Meng, Yilong Yin, Gongping Yang, Xiaoming Xi
2013 Sensors  
Retinal identification based on retinal vasculatures in the retina provides the most secure and accurate means of authentication among biometrics and has primarily been used in combination with access  ...  However, some shortcomings like the difficulty of feature extraction and mismatching exist in SIFT-based identification.  ...  In addition, the angular partition based method [27] [28] [29] has also been used in retinal identification.  ...
