The accepted answer is outdated as newer versions of Emgu CV have been released where the Image<Bgr, byte> object does not have a ToBitmap() method. To convert an instance of Image<Bgr, byte> to Bitmap object then you need to get a byte array from the image and then use the byte array to build a memory stream object then pass the memory stream object to the Bitmap constructor overload that takes a Memory Stream object parameter.

//load an image into an Image<Byte, byte> object
var image = new Image<Bgr, byte>("file.png");
//get the jpeg representation of the image
var arr = image.ToJpegData(95);
//get a memory stream out of the byte array
var stream = new MemoryStream(arr) ;
//pass the memory stream to the bitmap ctor
var bitmap = new Bitmap(stream) ;
//TO DO with bitmap

You can just use the ToImage() method to get a System.Drawing.Bitmap (which is a derived class of System.Drawing.Image), so something like this

// create an Emgu image of 400x200 filled with Blue color
Image<Bgr, Byte> img = new Image<Bgr, byte>(400, 200, new Bgr(255, 0, 0));

// copy to a .NET image
System.Drawing.Image pMyImage = img.ToBitmap();

Is that what you mean?
