You may want to read up on the chapter of Emgu CV discussing working with images here:
Working with Images - Emgu CV: OpenCV in .NET (C#, VB, C++ and more)[^]

Quote:
Unlike the Image<,> class, where you will need to pre-allocate memory with the correct size before passing it as an IOutputArray, when an empty Mat is passed as an IOutputArray, Open CV will automatically allocate memory for the Mat. You can also load an image from file using the CvInvoke.Imread function:

There have been plenty of articles posted on CodeProject over the last several years; you may want to read through them and see the various techniques in action:
