数字水印算法实现盲水印的嵌入提取，里面有图片(blind digital watermarking)

说明：  对图形进行二维傅里叶变化后的频谱进行中心化(Centralization of the spectrum after two-dimensional Fourier transform)

使用傅立叶变换对图像的条纹噪声进行滤除，分别使用了理想低通滤波、巴特沃兹低通滤波和高斯低通滤波进行处理(The use of Fourier transform on the image to filter out the noise of the stripes, respectively, using an ideal low-pass filtering,巴特沃兹Gaussian low-pass filtering and low pass filter to deal with)

说明：  matlab实现基于稀疏表示的高光谱图像分类(Hyperspectral image classification based on sparse representation using MATLAB)

BCS代码稀疏重构Lena.bmp图像，包中含有代码和图片本身，题主给了一定注释，便于CS初学者学习(BCS code sparsely reconstructs Lena. BMP image. The package contains code and image itself. The theme is given a certain comment, which is convenient for CS beginners to learn.)

基于arnold变换加密图像（带解密的代码），缺点是具有周期性(Encryption based on Arnold transform (with decryption code), the disadvantage is cyclical.)

ELMAN计算方法，改进的算法,非常好用(ELMAN calculation algorithm, the improved，use very well)

计算图像的几何不变矩—Hu矩，以及图像的相似度，在vc下实现。(Calculate the geometric image invariant moments-Hu moments, as well as the similarity of the image, achieved under vc.)

实现landsat处理，有兴趣的可以下载(Implementing Landsat processing)

基于sift算法的图像匹配。并用RANSEC算法去除错误匹配。最后还给出了sift算法的图像拼接。(Sift-based image matching algorithm. And use RANSEC algorithm to remove false matches. Finally, given the sift algorithm for image stitching.)
