医学图像融合的效果评价方法有很多,如信息熵、 互信息、均方值、峰值信噪比和平均梯度等。
There are many kinds of image fusion methods, such as information entropy, mutual information, mean square error, peak signal to noise ratio and mean grads.

经试验证明,这是一种有效的编码方法,在相同压缩比率下提高了重建图像的峰值信噪比PSNR。
Experimental results show that the improved hybrid image coding can improve the PSNR of the rebuilded image at the same compression ratio.
