After fixing some errors, it seems my OF is working. [](" imageanchor=“1” style=“clear: right; float: right; margin-bottom: 1em; margin-left: 1em;)

Image I1 [](" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;)
first iteration OF 1st iteration of warped I1
Second Iteration OF Second iteration of warped I1
3 iteration Of 3rd iteration of warped I1
Last iteration

Some strange results for another image pair:

I0 I1
1st iteration 2nd iteration
5th iteration 8th iteration
10th iteration
