Rezumat:

The present paper describes an iris binary code extraction procedure based on Hilbert Transform. The strong analytic signal associted with the chromatic iris sequence is used to recover the phase information which it contains. A meaningful synthetic example is given in order to illustrate the iris binary code extraction. The reasons for canceling the discovery of the radial iris features and for choosing to encode iris features only in the angular direction are also explained here. Gabor Analytic Iris Texture Binary Encoder is introduced showing that accurate recognition of similar iris images can be achieved comparing the binary iris codes that the encoder will generate from the similar circular iris rings (segments) previously extracted through Circular Fuzzy Iris Segmentation procedure. A new approach to iris recognition based on Circular Fuzzy iris Segmentation and Gabor Analytic Iris Texture Binary Encoder is tested here. Experimentally results obtained using the Bath University Iris Database are also presented.
