说明：  给图像添加噪声，驱除噪声，具体的说就是先添加高斯噪声等等，然后通过中值滤波，自适应滤波等等(Add noise to the image, get rid of noise。Specifically, it is the first toadd Gaussian noise, etc., and then median filtering, adaptive filtering, etc. )

通过matlab来实现遗传算法，利用遗传算法程序和遗传算法工具箱来实现该功能，具体应用效果很好(Matlab achieved through the genetic algorithm, the procedure using the genetic algorithm and genetic algorithm toolbox to achieve the function of specific application of effective)
