频域滤波
说明: 编程实现灰度图像的频域滤波算法。使用Matlab实现不延拓和延拓两个版本。对于延拓和不延拓版本,在理想低通滤波器、巴特沃斯低通滤波器和高斯低通滤波器上比较两者的区别;对于延拓版本,比较不同参数设置对上述三种滤波器滤波结果的影响。(Program to realize the filtering algorithm of gray image in frequency domain. Matlab is used to realize two versions of no extension and extension. For the extension version and the non extension version, the differences between the ideal low-pass filter, Butterworth low-pass filter and Gauss low-pass filter are compared; for the extension version, the effects of different parameter settings on the above three filter results are compared.)

简单起见,这里设定阈值为122,即最大灰度的一半(the sake of simplicity, this threshold value is set to 122, the largest gray half)

行人检测
说明: 基于MATLAB的行人检测。直接运行imhogtrace主程序,即可得到运行结果。针对不同的图像,需要调整参数,我放的这张图,虽然效果不好,但是可以提供参考意义(Pedestrian detection based on MATLAB. Run the main program of imhogtrace directly to get the running result. For different images, parameters need to be adjusted. Although the effect of this picture I put is not good, it can provide reference significance)

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)
