An Efficient and Fast Iris Location Algorithm
Chun Lei Shi, Guang Yuan Jiang, Haiyan Qi, Fei Han · Applied Mechanics and Materials · 2012
The edge information of pupil was extracted by the least-square method, and the iris outer circle was extracted by the improved Canny Operator plus Hough Transform. The segmental-secondary linear localization method adopting edge detection and Radon Transform was proposed to remove the noise from eyelid on the eyelid localization, the eyelash noise and eyelid shadows were removed by threshold method.
