得到当前光标点的RGB值，移动光标，EDIT就可以显示出颜色RGB值。

rgb图像转换成YCbCr，matlab视频采集某几帧并转换为二值图像和YCbCr图像-RGB images are converted into YCbCr, matlab video capture a few frames and converted to two value images and YCbCr images

利用IDL实现对图像处理的界面，包括对灰度值和RGB进行设置的按键程序的源代码，比较简单(Using IDL to achieve the gray value of the image settings button program source code, relatively simple.)
