C#通过Emgu这个图像处理库，可以很方便的将一幅单通道图像分割为R、G、B三个单通道图像。
Image<Bgr, Byte> ImageBGR = null;
Image<Bgr, Byte> ImageSrc = null;
Image<Bgr, Byte> ImageB = null;
Image<Bgr, Byte> ImageG = null;
Image<Bgr, Byte> ImageR = null;
Mat one_channelB;
Mat one_channelG;
Mat one_channelR;
private void Form1_Load(object sender, EventArgs e)
{
ImageSrc = new Image<Bgr, Byte>(path);
ImageBGR = ImageSrc.Clone();
CvInvoke.Split(ImageBGR, vm);
var vms = vm.GetOutputArray();
one_channelB = vms.GetMat(0);
one_channelG = vms.GetMat(1);
one_channelR = vms.GetMat(2); pb_imageRgb.Image = ImageBGR.Bitmap;
pb_imageR.Image = ImageR.Bitmap;
pb_imageG.Image = one_channelG.Bitmap;
pb_imageR.Image = one_channelR.Bitmap;
}
