大津阈值分割法，也称最大类间方差法，利用图像的灰度分布密度函数定义图像的交叉熵。
交叉熵可看作是两个概率系统（即图像背景及目标）的信息量之间的差异。求出的交叉熵越大，则分割效果越好。

图像清晰度评价函数说明
1、熵: 表示图像所包含的平均信息量的多少,嫡值越大则所含信息量越多。
文件名：entropy.m 结果：EN
2、交叉嫡：反映两幅图像的差异,交叉嫡越小,则融合图像和原图像的差别越小。
文件名：cross_entropy.m 结果：平均交叉嫡MCE，均方根交叉嫡RCE
3、峰值信噪比: PSNR越高,说明融合效果与质量越好。
文件名：psnr.m 结果：PSNR
4、Qabf: 评价边缘或梯度质量，越大边缘越明显
文件名：Qab
