从特征函数的角度将盲分离技术应用到图像的盲分离中去.提出对照函数为二次特征函数的四阶导数,采用特征函数的高阶导数的矩阵张量方法,通过正交对角化实现图像的瞬时盲分离.实验结果表明,盲分离后的信息在概率分布上与信源的概率分布具有相近的特征,表明此技术对于盲信息分离具有良好的分离效果,可以应用到信息盲分离中去.
The blind separation technique is applied to the blind separation of images from the perspective of eigenfunctions. The control function is the fourth derivative of the quadratic eigenfunction. The matrix tensor method of higher order derivatives of eigenfunctions is adopted. By orthogonal diagonalization The experimental results show that the probability distribution of blind information is similar to the probability distribution of information source, which indicates that this technique has a good separation effect for blind information separation and can be applied to information blind separation Go in.
