Abstract: This paper presents a novel iris texture features extraction algorithm based on zero spectral moment filters (ZSMF). After preprocessing, the iris image was decomposed via ZSMF in order to get more exact iris texturefeatures. Experimental results show that the speed of the algorithm is fast and the algorithm is efficient.

Key words: zero spectral moment filters, iris texture, features extraction
