A Highly Efficient Biometrics Approach For Unconstrained Iris Segmentation And Recognition, Yu Chen
A Highly Efficient Biometrics Approach For Unconstrained Iris Segmentation And Recognition, Yu Chen
FIU Electronic Theses and Dissertations
This dissertation develops an innovative approach towards less-constrained iris biometrics. Two major contributions are made in this research endeavor: (1) Designed an award-winning segmentation algorithm in the less-constrained environment where image acquisition is made of subjects on the move and taken under visible lighting conditions, and (2) Developed a pioneering iris biometrics method coupling segmentation and recognition of the iris based on video of moving persons under different acquisitions scenarios. The first part of the dissertation introduces a robust and fast segmentation approach using still images contained in the UBIRIS (version 2) noisy iris database. The results show accuracy estimated …
