1. A method of identifying an individual by iris image-based recognition system comprising the steps of:

  • obtaining an iris image of said individual to be identified by locating the outer boundary and the inner boundary of an iris, whereby said inner boundary of said iris is localized using maximum vote finding method;

    processing said localized iris image to extract iris features by transforming said localized image into a polar coordinate system;

    extracting the characteristic values of fractal dimension from said image area for generating an identification code; and

    comparing said characteristic values of said extracted identification code with the characteristic values of a previously stored identification code of said individual.
