摘要
通过对独立分量分析算法的研究,介绍了该算法的基本模型及目前应用最广泛的快速定点ICA算法的数学原理.通过仿真试验结果表明,用该算法对随机混合的3幅图像进行盲分离,取得了理想的效果.
Independent Component Analysis is a new signal processing method which develops rapidly during last few years. This paper introduces the basic model of the algorithm, analyzes the math principle of frequently-used rapid fixed-point algorithm for independent component analysis, and applies the algorithm in blind separation of three images which are mixed randomly. The result shows that the algorithm is effective and reliable.
