Nonlinear scale-space based boundary localization for nonideal iris
A nonlinear scale-space based localization method of nonideal iris boundaries was proposed.The method eliminates small-scaled geometric structures while preserving large-scaled iris boundaries by nonlinear diffusions with the scale-evolution property.Moreover it combines such diffusions with the fra...
