A Survey of Techniques for Digital Watermarking

通过配置文件实现动态菜单的添加，有分析文件程序与解析，然后还不够完善，结构清晰，便于学习的。

GDI中提供的各种绘图方法LineTo(), Ellipse()等等，都没有考虑过锯齿形状的消除，于是诞生了本代码，它实现了近乎实时的消除图形锯齿的方法。

粒子系统的一个原代码文件，很有用处。有需要的可以参考-Particle system, a source code file, very useful. Can refer to those in need

OTSU方法计算图像二值化的自适应阈值，OTSU 算法可以说是自适应计算单阈值（用来转换灰度图像为二值图像）的简单高效方法。下面的代码最早由 Ryan Dibble提供，此后经过多人Joerg.Schulenburg, R.Z.Liu 等修改，补正。算法对输入的灰度图像的直方图进行分析，将直方图分成两个部分，使得两部分之间的距离最大。划分点就是求得的阈值。都是老外写的，经典哦。-OTSU images calculated value of the two adaptive threshold, OTSU algorithm can be calculated adaptive threshold (for conversion to gray scale images binary images), a simple and efficient manner. The following code from the earliest to provide Ryan Dibble, after a more than Joerg.Schulenburg, R. Z. Liu amend the correction. Algorithm for the importation of gray-scale image histogram analysis of histogram is divided into two parts, Part 2 makes the distance between the largest. Demarcation point out the threshold. Foreigners are written in the classical oh.

knn k近邻算法，可选择欧式距离或者曼哈顿距离-knn k nearest neighbor, Euclidean distance or Manhattan can choose the distance
