Image compression and comparison

31
I have two images. one is a CAD diagram and another is a scanned picture. They are not in the same scale. The CAD diagram is my original. I need to resize the scanned picture to the sme scale as the CAD diagram and compare to find out how these both differ.

Please help me find a strategy to program. Should I use Matlab or VB? What is a better approach to the problem?
