Description: 本程序是基于单幅图像的超分辨率算法，通过对输入的高分辨率图像进行下采样得
% 到原始低分辨率图像，对输入的低分辨率图像插值后，利用DWT将低分辨率图像分
% 解为不同的4个子带；同时直接对对分辨率图像进行SWT处理。由SWT得到的高频子
% 带来修正DWT得到的高频子带。最后，通过逆离散小波变换（IDWT）组合修正的高
% 频子带和低分辨率图像，得到输出的超分辨率图像。通过计算PSNR和SSIM评价结果。(This program is a super-resolution algorithm based on a single image, which is sampled from the high resolution image of the input.
% to the original low resolution image, after interpolating the input low resolution image, the low resolution image is divided by DWT.
The% solution is different 4 subbands, and the resolution image is processed by SWT. High frequency subsets obtained by SWT
% brings the high frequency subband obtained by the modified DWT. Finally, the height of the combination of inverse discrete wavelet transform (IDWT)
% frequency subband and low resolution image, and the output super-resolution image is obtained. The results were evaluated by calculating PSNR and SSIM.)

Description: 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：Qabf.m 结果：Qabf（QAB/F)
5、平均梯度（Average Gradient）:也称为清晰度，反映了图像中的微小细节反差与纹理变化特征，同时也反映了图像的清晰度，越大越好。
文件名：avg_gradient 调用：outval = avg_gradient(img)
6、结构相似性指数： SSIM指原图像和融合图像的相似程度,值越大越相似
文件名：ssim.m 结果：SSIM
7、互信息：MI(mutual information)
8、NMI: Normalized mutual information(Image sharpness evaluation function)
