图像清晰度评价指标Matlab
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)
