中文说明：实现了图像的加水印，去噪，加噪声等功能，是小学期课程设计的题目，快速扩展随机生成树算法，借鉴了主成分分析算法（PCA），仿真效果非常好，到达过程是的泊松过程。
English Description：
To achieve the image plus watermark, denoising, coupled with the function of the noise is the title of primary phase of the curriculum design, the rapid expansion of the random spanning tree algorithm, drawing on the principal component analysis (PCA) algorithm, the simulation effect is very good, the arrival process is Poisson process.
