有较好的参考价值，实现了图像的加水印，去噪，加噪声等功能，一种流形学习算法（很好用）。- There are good reference value, Realize image watermarking, de-noising, plus noise and other functions, A fluid manifold learning algorithm (good use).

目前最新的最有效的去水印算法，是google研发的(At present, the latest and most effective watermarking algorithm is developed by Google)
