the desirable .
I am writing some of the iterations during the registration process.

0 1.04009 [0.977812, 0.0250499, 97, 60, -0.0179536, 0.498556]

498 1.02966  [0.894303,  -0.157513, 96.9616, 59.9319, 1.18778, -0.165064]

result:
500  1.02962  [0.894281, -0.15757, 96.9616, 59.9321, 1.18874, -0.165108]

I have to use Similarity2D Transform, because the images need scaling too.
