中文摘要：

简要介绍了独立分量分析的基本数学模型和算法，在此基础上探讨了独立分量分析在有噪混合图像分离中的应用，提出了一种结合维纳滤波去噪与独立分量分析相结合的解决方法。实验结果表明，该方法能有效地降低噪声信号的影响，较好地恢复了原始图像。

英文摘要：

The basic mathematic model and algorithm of independent component analysis and the apply of independent component analysis in noisy mixed images was discussed, a method was proposed of combining Wiener filtering de-noising and independent component analysis. The results show that this method can reduce the affect of noise, accordingly renew the original image.
