Investigation of the Algorithm for Iris Localization
Lian Qiu-sheng · Video Engineering · 2006
For the purpose of localizing iris precisely and quickly, an improved iris localization algorithm is proposed while based on introducing some prevailing localization algorithms. In this method, inner boundary are localized by thresholding the images and Freeman′s chain code. Canny operator and circle Hough transform are used to localize outer boundary, and the eyelid is removed by Canny operator and linear Hough transform. The method of thresholding is used to remove the eyelash and mirror reflection. Experimental result shows that our algorithm is rational and feasible.
