Hardware implementation of a novel edge-map generation technique for pupil detection in NIR images
Engineering Science and Technology, an International Journal, 2017 This paper proposes an edge-map generation technique for pupil detection in near infrared (NIR) images and its hardware implementation. The proposed edge-map generation technique is based on generating two different edge-maps of same eye image using ...

Pupil Localization by a Template Matching Method.
Proceedings of the International Conference on Computer Vision Theory and Applications, 2013 In this paper, a new algorithm for pupil localization is proposed. The algorithm is based on a template matching approach; the original contribution is that the model of the pupil that is used is not fixed, but it is automatically constructed on the first frame of the video sequence to be examined.

Tailoring Anderson localization by disorder correlations in 1D speckle potentials
, 2013 We study Anderson localization of single particles in continuous, correlated, one-dimensional disordered potentials. We show that tailored correlations can completely change the energy-dependence of the localization length.
