基于细菌趋药性算法的盲图像分离方法

提出了一种新的基于细菌趋药性(BC)算法的盲图像分离方法,利用图像信号的规范四阶累积量作为目标函数,使用BC算法对目标函数进行优化以实现图像的盲分离。每分离出一幅图像后,从混合图像中消除该幅图像成分后再进行下一次分离,从而最终实现所有源图像的逐次分离。仿真结果表明,本文算法能够有效实现对多幅混合自然图像的盲分离,且具有较好的分离效果。

Blind image separation method based on bacterial chemotaxis

A new blind image separation method based on bacterial chemotaxis(BC) is proposed.In this method,normalized fourth-order cumulant was used as objective function and the bacterial chemotaxis algorithm was used to optimize it for blind image separation.The separated source image component was wiped off from the mixed image before the next separation process and other source images could be separated one by one.Simulation results show that the proposed method can achieve the blind separation for mi...
