For lots of low quality iris images which obtained from different sensors at different periods of time,using the image fusion tech nology to process it.According to the non-rigid deformation characteristics of iris image zoom pupil,proposed using curve fitting technol ogy in iris image registration.Then the registered iris image using pixel level fusion method of wavelet fusion for fusion,the ultimate aim is to make the missing pieces information of low quality iris images fused into an iris image which contains richer informations,and build a new iris image database for the field of iris recognition..The experimental results show that this method has futrher promoted the accuracy of low quality iris images recognition.
