    实现两幅图像的配准,首先对图像做高斯低通滤波处理 ,然后计算互信息值,利用PWELL算法求出最优的参数,根据所得参数进行配准(To achieve the registration of two images, the first image to do the Gaussian low-pass filter, then calculate the mutual information value, use PWELL algorithm to determine the optimal parameters, in the light of registration parameters)
