为数字图像水印提供多种攻击方式，其中包括JPEG压缩、高斯低通滤波等多达十种攻击方式。(Offers a variety of attacks of digital watermarking ,including the jpeg compression, Gaussian low-pass filtering, up to ten different attacks)

C#实现多边形颜色的填充，主要是种子填充和种子扫描线填充两种算法。(C# implementation of the polygon fill color, mainly seeds and seed filling scan line fill two algorithms.)

图像分解算法，四种方法可选，包括threshold, K means threshold, region growing以及gradient based segmentation(Image decomposition algorithm, four methods available, including the threshold, K means threshold, region growing and gradient based segmentation)

时移相位差校正法，通过时移，进行前后两次FFT分析，利用离散频谱对应峰值谱线的相位差以求出频率和相位校正量。(Phase difference correcting method by time-shifting. Make two FFT analysis before and after the time-shifting,and make use of the phase difference of the peak spectral lines to get frequency and phase correction amount.)

将图像转换到HSV空间，并对其进行量化降维后，计算其颜色直方图(Image conversion to HSV space, and to quantify the dimensionality reduction, the calculation of its color histogram)
