基于DCT方法的数字水印论文5篇，对学习基于DCT方法的数字水印初学者会有帮助。可以了解基于DCT的水印基本方法。(DCT-based method of digital watermarking papers 5, to learn methods of digital watermarking-based DCT would be helpful for beginners. DCT-based watermark can learn the basic method.)

能够实现对SAR图像和其他类型的包含大量噪声的图像进行平滑去噪，在去除噪声的同时还能保持并增强边缘，适用于目标提取。(SAR images can be achieved and other types of containing large amount of noise in the image smoothing denoising, remove the noise while maintaining and enhancing the edge, suitable for object extraction.)

说明：  用matlab工具去除照片中水印，去除水印快速，简单，快速(Using Matlab tool to remove watermarks in photos is fastly, simplely.)

Image_processing in C

OPENCV做图像变形的经典代码啊，适合比较初级的同学看看(OPENCV do image warping the classic code ah, suitable for elementary students to see more)

初学者的游程编码，可以进行小图像的压缩，可以以此为基础进行编码和参考(RLE beginner, you can make small image compression, can be encoded as a basis and reference)

图像分类程序，此图像分类采用 SIFT + Kmeans 聚类的方法，然后调用 MLP 对其特征进行分类处理，速度实现比较快，正确率高(Image classification procedures, the use of this image classification method SIFT+ Kmeans clustering, and then call the MLP classification of its features, faster speed to achieve the correct rate)

ksvd 其中包含omp算法,对一副自然图像进行稀疏重构，重新形成该图像，找出稀疏系数。(ksvd method.if you want konw more detail please translate the above Chinese words.)

视频插帧中的双向运动估计算法，注释很详细。利用双向运动估计，计算内插帧运动矢量场(Bidirectional motion estimation, is used to calculate interpolation motion vector field)
