算差分盒维数的matlab程序。 让窗口中的每个像素都对分数维作出贡献。首先,计算某一尺度窗口的平均灰度值 ,然后判断每一个像素的灰度 ,若大于灰度平均值 ,则累加其灰度值为 max ,若小于灰度平均值 ,则累加其灰度值为min ,用max 和min代替 在 Sarkar 和 Chaudhuri 算法中的最大值和最小值 ,再通过拟合求出分数维。 -Differential count box dimension matlab program. Let window on the fractal

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
