Abstract: This paper is proposed a new method for iris identification based on multiwavelet transform. By means of the mathematical properties of CL multiwavelet, the iris texture feature can be presented accurately and primely. The subbands are coded and the information of direction cosine is used for iris matching, by means of which this method overcomes zoom, shift and illuminance and obtains approving effect.

Key words: iris identification, multiwavelet transform, texture feature
