摘　　要：盲源分离图像加密是一种可靠、具有极高安全性的图像加密方法。盲源分离依据源信号之间的相互独立性把混合信号分离开,最终得到源信号的估计。在应用ICA算法对图像进行解密时,盲源分离的不确定性可能会给解密过程带来困难,因此,通过盲源分离对图像加密的方法也会受到一定的约束。本论文旨在用多种不同的ICA算法对加密图像进行解密,并将这几种ICA算法进行对比分析。Blind source separation image encryption is a reliable,high security of image encryption methods.The blind source separation divides the mixed signals according to the mutual independence between the source signals,and finally obtains the estimation of the source signals.When using ICA algorithm to decrypt the image,the uncertainty of blind source separation may bring difficulties to the decryption process.Therefore,the method of image encryption by blind source separation will also be constrained.The purpose of this thesis is to decrypt the encrypted images with a variety of ICA algorithms,and to compare and analyze these ICA algorithms.
