The Research Based On Indentity Recognition System Of Iris

With the development of the technology, An accurate personal identification is the most critical hinge of a safe system chain. Traditional personal identification methods (e.g., passwords, PIN) suffer from a number of drawbacks and are unable to satisfy the security requirements of our highly inter-connected information society today. Biometrics-based personal identification has been a important research. As one of biometrics-based personal identification, Iris identification is a method which is used to identify one personal figure with the Iris texture.Because of stability, uniqueness and difficulty in manual change, Iris identification is one of the most accurate biometrics-based personal identification.It consisted of two parts in this paper:Firstly,some new methods were presented in Iris image preprocessing,Iris image locating,character extract and matching based on the research of some key technology and arithmetic about image processing and pattern recognition technology.And based on these methods an iris-based biometric personal identification system.Secondarily,character extract arithmetic based on Morlet wavelet transform was presented.Algorithms attain the phase information of the texture character points with one dimension and two dimension Morlet complex wavelettransform according to the different Iris area and attain the code of Iris image character.At last, by calculating the hamming distance between two compared Irises a judgement was given. The result shows that this approach has a very high speed of operation and good result and can be used to actually Iris recognition system.
