Hi Milenko,
One solution is to display the image (using etiher imshow, imagesc...), call "hold on", then plot the points at the specified (x,y) coordinates. If your points are in geographical coordinates, you need to convert their coordinates into (i,j) image index. An alternative is to specify the 'xdata' and 'ydata' when you call imshow, then you axis is directly in the geographical unit.
Hope this helps, David
