Interface problem?

Hello guys,

It's been quite a while since I wrote my code so now I am in trouble to manage to run the code for this function below. I am trying to do some image processing and then try to OCR it via tesseract. But the problem is I couldn't find out how to run the code below.

Here is the method I would like to call:

http://www.emgu.com/wiki/files/3.0.0-alpha/document/html/07038386-9f0e-1fa4-8e7c-7ec31b3b2a8f.htm

But I couldn't manage to set the parameters successfully:

IInputArray src, 	IOutputArray dst,

Here is what I tried to do:

Emgu.CV.IInputArray[] iarr;

Emgu.CV.IOutputArray[] oarr;

foreach (var image in images.OrderBy(key  => key.Value.Position.X ))          {

iarr = new Emgu.CV.IInputArray[1];

iarr.SetValue(image.Value.img, 0);                                            oarr = new Emgu.CV.IOutputArray[1];

arr.SetValue(image.Value.img, 0);

CvInvoke.CopyMakeBorder(iarr[0], oarr[0], 12, 12, 12, 12, Emgu.CV.CvEnum.BorderType.Default);

It gives error when I try to set a value because it is an Interface. So I decided to implement a class using this interface but couldn't go much further. Any help would be great.

 public class CMB : Emgu.CV.IInputArray

public InputArray[] arr;

public InputArray GetInputArray()

return arr[0];

public void SetInputArray(Dictionary img)
