IRIS SEGMENTATION USING GA BASED CIRCULAR HOUGH TRANSFORM (GACHT)

Iris recognition system consists of a sequence of stages, each stage perform specific functions on the captured image of the human iris. the first stage is automatic segmentation of iris from the eye image. in this paper, new proposed algorithm designed and implemented using genetic based hough transform algorithm (gacht) to implement the first stage of iris recognition system with the developed genetic algorithm. gacht was used to detect the iris and pupil segments which in turn is a outer and inner circles, the accuracy of any iris recognition system should be depend on the right region of the iris, which is done in this paper using and evolutionary algorithm called gacht algorithm
