An algorithm of approximate location of iris center in image is presented. It is based on Hough transformation for circles. Problem is set in a way to detect only iris center position without evaluating its size. Such formulation allows to reduce the dimension of parameter space compared to commonly used approaches that detect center position and radius simultaneously. Apart, omitting radius estimation gives an opportunity to use points of both pupil and iris circles in Hough transform, increasing the stability of method especially for images with poor pupil contour quality. The algorithm was tested for more than 95000 iris images from public domain databases.
