平衡多小波及在虹膜图像压缩中的应用

Iris recognition system with high performance and high confidence is now more efficient biometric security techniques. The theory of balanced multiwavelet is a recent generalization of multiwavelet and become a hotspot because of avoiding pre-filtering. In this paper, we presents a new approach on the construction of orthogonal balanced multiwavelet. The experimental result of applying in iris image compressing indicated that it outperforms GHM and CL in terms of peaksignal-to-noise ration and eigenvalue of variance estimator.
