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)

FCM
利用模糊C聚类(FCM)的方法对彩色图像进行分割,期中可以用不通的特征向量来表征图像的特征(The method of fuzzy C clustering (FCM) is used to segment the color image. In the period of time, the feature vectors can be used to characterize the features of the image.)

main
将保存有灰度图像信息的txt文件转化生成灰度图片。 txt数据只能包含数据,数据用逗号或者空格隔开,所存数据个数应与所生成的图片大小相同。例:要还原的图片大小为640*480,那么txt文件中就应当有307200个数据。(The txt file with information of grayscale image is transformed into gray image. The TXT data can only contain data, separated by commas or spaces, and the number of data stored should be the same as the size of the generated image. Example: the size of the image to restore is 640*480, so there should be 307200 data in the txt file.)

二值图开运算
说明: 将原图二值化处理后,对二值图像进行腐蚀处理去掉图中主体以外的噪点或小斑迹(After binarization of the original image, the binary image is corroded to remove the noise or small spots outside the main body of the image)
