Bi-Local Region Based Iris Segmentation Framework for Less-Constrained Visible Wavelength Images

Iris recognition systems often degrade in performance when the subjects' cooperation is not expected in a less-constrained environment captured from a greater distance by visible wavelength imaging system. Algorithms in this field have reported inaccurate segmentations due to non-circular geome...
