ICA独立成分分析，利用混合信号解出各个独立信号，被用于图像解混。-ICA Independent component analysis, the use of mixed-signal solution of the individual signals to be used for image unmixing.

互信息盲源分离,这基于这么一个事实,混合信号的互信息最小时(Mutual information blind source separation, which is based on such a fact, mixed signal with minimum mutual information)
