摘要:Currently, a number of biometric identification having been implemented as components of a variety of security system are fingerprint, palm geometry, face, facial thermo-graph, hand vein, signature, speech, eye iris and retina. It has been identified that the iris of the eyes has unique pattern/texture and color characteristics for every single individual, so that it has now been used as a component of a biometric system. A number of iris identification algorithms have been developed and applied in security systems; however, because such algorithms have only been based on the iris pattern characteristics, the results have not yet been optimum. This is caused by the fact that the result of extracting iris patterns is quite susceptible to the changes of light intensity and the movement of position in the process of iris image acquisition. This paper proposed a new model of identifying an iris based on an iris color with the aid of a 3-dimension color bin histogram. The advantage of using iris colors is that they are not quite sensitive to even small changes of light intensity and position. This kind of model has successfully been implemented as a system prototype by integrating a number of algorithms developed in the research. The trial run has been carried out by the use of a database containing 1877 iris images and 322 samples of test images. The analysis result indicates that the accuracy level of the developed system is relatively very good with the error rate of around 8 %.
