C++ 写的一些算法模板 ，比如Kruskal、KMP、欧几里德算法、最大匹配(匈牙利算法)、最小费用最大流、字符串的哈希方法、增广路算法、网络最大流_邻接表等……(C++ write some algorithms template, such as Kruskal, KMP, Euclid arithmetic, maximal matching (Hungary) is proposed, the minimum cost and maximum flow, string hash method, augmented road algorithm, network maximum flow _ adjlink etc......)

说明：  利用双线性插值法，来对图像进行放大或者缩小的操作(Bilinear interpolation is used to enlarge or shrink the image)

说明：  图像超分辨是目前国内外研究的热点，该算法主要用于光学图像的超分辨(Image super-resolution is the study of hot spots at home and abroad that the algorithm is mainly used in optical image of the super-resolution)

将原始载体图片经过一维冗余离散小波变换分成四个子频带，分别对每个子频带进行奇异值分解， 将水印图片灰度值直接按比例缩小嵌入到奇异值矩阵中，再将此矩阵进行一次奇异值分解得到奇异值当做此子带的奇异值， 重建此子带矩阵，而后将进行反冗余离散小波变换得到嵌入载体后的水印图像。(The original image after the one-dimensional vector redundant discrete wavelet transform is divided into four subbands, respectively, of each sub-band for the singular value decomposition, the watermark image gray value scale down directly embedded into the matrix singular value, then this matrix is ​ ​ a Singular value decomposition singular value as the singular values ​ ​ of this sub-band, the reconstruction of this sub-band matrix and after anti-redundant discrete wavelet transform watermark image after embedding the carrier.)

利用surf算法,来实现图像间的拼接,并可将其推广为多幅图之间的拼接融合。(Realization of two images splicing)

说明：  简易的在c#中利用gdal来读取遥感图像(Using GDAL to read remote sensing image in C)

说明：  matlab编写的图像处理程序，用于提取图像的纹理、颜色特征。(matlab image processing procedures to prepare for the extraction of image texture and color features.)

自编语谱图函数，可实现基本的spectrogram功能(Self compiled spectral function, which can implement basic spectrogram functions)
