可以识别图像的边缘,提取图像边缘轮廓,且程序简单易懂,方便初学者学习。(You can recognize the edges of images.)
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)
利用matlab进行图像数据的剪裁,需要提供需剪裁影像的中心点行列号;RMSE.m是计算均方根误差RMSE的程序。(Using MATLAB to tailor the image data, we need to provide the central point and row number of the image to be tailored. RMSE.m is a program to calculate the root mean square error RMSE.)
