PSNR

传统图形细化算法，每条代码有详细注解，适合新手。(Traditional graphics thinning algorithm, each code have detailed notes. )

说明：  Wallis滤波可以有效去除影像的不均匀光照现象，因此使用Wallis滤波进行阴影去除算法(a kind of shadow removal algorithm which combining with Wallis filter)

Multiclass Spectral Clustering Algorithm，和Dominant-set算法同属于较常用的聚类算法，用于图像分割等(Multiclass Spectral Clustering Algorith m, and Dominant-set algorithm is more commonly used with the clustering algorithm for image segmentation, etc.)

采用了小波变换的方法实现了红外光图像与可见光图像的融合，并且设计了一个简单的matlab GUI界面。小波变换的分解层数为2层，采用低频平均高频取大的融合规则，融合效果非常欢迎下载。(The method of wavelet transform is used to realize the fusion of infrared and visible light images, and a simple matlab GUI interface is designed. The number of decomposition layers of the wavelet transform is 2 layers, and the fusion rule is adopted by the low frequency average high frequency. The fusion effect is very welcome to download.)
