使用directshow代替opencv的vfw的源代码。代码是工程中需要引入的文件。配置好opencv，按照文章的步骤做就可以了。-Replace the use of DirectShow opencv source code of the VFW. Code is a need to introduce engineering documents. Configured opencv, article in accordance with the steps to do it.

数字图像处理,离散余弦dct变换域中水印的提取-digital image processing, discrete cosine transform domain Extra watermark extraction

图像420转换为422或444的算法。高斯加噪算法，脉冲加噪算法。-YCbCr 4:2:0 image is converted to 4:2:2 or 4:4:4 of the algorithm, Matlab program is

本代码实现的功能：24位位图（BMP）的灰度化。具体实现过程：打开图像文件,找到数据区(每3个字节代表一个象素的R,G,B值),循环扫描,根据RGB的权重,计算出灰度值. 如果要得到256色灰度图,则要新建一个调色板,修改信息头和文件头.-Realize the function of the code: 24-bit bitmap (BMP) of the gray. Concrete realization of the process: Open the image file, locate the data area (3 bytes per pixel on behalf of a R, G, B values), cyclic scan, according to the weight of RGB, gray value is calculated. If you want to get 256 colors grayscale, would create a new palette, modify the header and file header information.
