Optical approach for iris segmentation and tracking
Elhoussaine Ouabida, Abdelaziz Essadike, Abdenbi Bouzid · 2016
In this paper, an autonomous active contour model based on the optical correlation algorithm is proposed. Optical correlation is used to calculate iris and pupil areas with a digital simulation of the Vander Lugt correlator. This area term computation assists the model to define an initial contour and at a later stage, to calculate terms in the energy expression. In the proposed model, several reference images called filters of iris and pupil have been introduced. Applied to three iris database and iris motion video, the proposed model enables us to reach better segmentation and tracking accuracy performance of irises.
