Abstract :
A new iris identification algorithm with tree- structured wavelet transform and dominant frequency channel energy is represented in this paper . After the iris image is preprocessed firstly, the normalized iris texture image is obtained and the wavelet is decomposed on selected base. Secondly the decomposed path is determined through some restriction condition. And the selected energy channel and channel value are regarded as iris feature. Finally, the experiment result verifies the correctness and validity of the approach.
