IRIS Recognition System Study Based On SVM Algorithm

Biometric technology is the use of human physiological Charac- teristics or conduct its own characteristics, the identity of the person authorized to use the computer to identify an effective identification method. Iris has a unique personal characteristics like fingerprints : Furthermore, the iris is the part of the body open and easy to remote machine vision inspection, it is a non-invasive of the biometric identification technology.Iris Recognition System for the entire first part of the study :1) discussed the physiology of iris recognition based on the physiological structure of the iris, Iris physiology to explain the formation of the iris texture and physiological characteristics of the minor details, explain the physiological basis of the iris of the iris to ensure the universality, uniqueness, stability, acquisition, non-invasive and difficult-to-counterfeit features. Iris for the media to take full advantage of the Iris Recognition of physiological characteristics, and make comprehensive use of various image processing techniques and analysis methods, which is the most accurate way to identify the physiological characteristics.2)the study of the iris image preprocessing. Iris image preprocessing (iris location) is a prerequisite for iris feature extraction, image characteristics pretreatment has a direct impact on the accuracy of image feature extraction, and the final image recognition accuracy. Edge consists of three major steps : extract, iris and outside the boundary location, normalized iris image. Edge Extraction Method : This paper introduces the four gradient operator, Laplacian operator, Marr edge detection theory, Canny operator. Canny operator of the classical subject, according to the specific characteristics of sclera, the selection of appropriate parameter values of sigma and thresh the iris image edge extraction, test results show that good Canny operator can detect the edge of the iris image.Improved definition of the Hough transform the outside edge of the iris :...
