Overlay axis on an image

Hi All,

I have the following image of an fft peak where the peak is shifed a few pixels away from the origin. To better dispaly this I was hoping I could overlay a red cross to insect the 50, 50 point of the image.

Is there an easy way to do this?

Insert the marker on the image

%After Image Show/display
hold on;
[r,c]=size(image);
plot(round(c/2),round(r/2),'r*','MarkerSize',10);
