… distance based iris recognition on a benchmark database justifies that the linear features
of irises in their edge maps are significant enough to uniquely represent the irises. The …

… In this paper, we propose a novel descriptor which characterizes an iris pattern with multi-scale
step/ridge edgetype (ET) maps. The ET maps are determined with the derivative of …

… We start by determining the outer edge by first downsampling the images … maps the whole
iris even if some part is occluded by the eyelashes, while we map only the lower part of the iris …

… approach to detecting curvilinear edges is used to localize … outer iris boundaries support
an isometric mapping of the iris … pseudopolar mapping and its invariances for recognition will …

… To generate the edge map, a gray scale iris image is applied with edge detector. The … of
intensity values is the edge map. To select the proper scale of edge analysis and to smooth the …

… The Iris localization is carried out using circular Hough transform that detects the circular …
