MUSIC算法和ESPRIT算法的比较，同一目标不同信噪比下的性能曲线(MUSIC algorithm and the comparison of the ESPRIT algorithm, the same goal under different SNR performance curve)

When capturing an iris image under unconstrained conditions and without user cooperation, the image quality can be highly degraded by poor focus, off-angle view, motion blur, specular reflection (SR), and other artifacts. The noisy iris images increase the intra-individual variations, thus markedly degrading recognition accuracy. To overcome these problems, we propose a new iris recognition algorithm for noisy iris images.
