计算图像的均方误差和峰值信噪比，来评价图像的质量-MSE is calculated images and peak signal to noise ratio, to evaluate the quality of the image

er than mean squared error (MSE) function only. As an additional merit, it is also revealed that rigorous Mercer kernel condition is not required in FKNN networks. When the proposed architecture of FKNN networks is constructed in a layer-by-lay
