VC++实现数字水印技术，在BMP位图中添加各种水印信息，程序分LSB和DWT嵌入方法。(VC++ implementation of digital watermarking technology, adding various watermarks in BMP bitmap, the program points LSB and DWT embedding methods.)

opencv中对扫描图片的切边处理，并且对倾斜图片进行旋转矫正，(The cutting edge of the picture in opencv, rotation correction)

说明：  通过程序介绍的一些算法,可以对信息隐藏技术实施攻击,特别是水印技术.(procedures introduced by the algorithm, the information can be hidden to attack technology, in particular watermarking technology.)

里面包括24位真彩色图像类和其基础处理的类，包括灰度化，二值化和形态学操作(Includes 24-bit true color image processing based on class and class, including the gray-scale and binary morphological operations and)

取阈值常用的方法有：双峰法、迭代法、大津法（OTS(threshold for commonly used methods : bimodal, iteration, Tianjin (OTS. )

水平百叶窗显示图片，讲一张图像垂直分成若干份，bitblt一行一行的显示(The level of blinds show pictures, talk about an image vertically divided into several copies, bitblt display line by line)

图形学中的透视投影算法 在屏幕中心绘制立方体的透视投影 可以绘制一点透视图 二点透视图 三点透视图(Graphics in the perspective projection algorithm for drawing a cube in the center of the screen you can draw a little perspective projection perspective two point perspective three-point perspective)

matlab 图像处理方面的经典书籍，值得初学者仔细认真的学习(matlab image processing aspects of classic books, worthy of serious study carefully beginners)

将曲线轮廓中的B-样条曲线通过最小二分法转换成一组能保持曲线轮廓形状的小折线。这样，原有的字体轮廓数据就从用曲线轮廓表示转变为用多边形表示，即用一组点及其先后顺序来描述轮廓。(Profile to Polygon)

说明：  在大图中寻找到小图。 并圈出小图所在位置。 图片用picture控件显示。(In the big picture to find a small map. )
