Something About branch1

[Acmenwangtuo]

I see when you compute the pf,you use diff_branch1 but i cant find the diff_branch2 and I can see in your code comment:

    # Two branches. The CNN try to learn the H and inv(H) at the same time. So in the first branch, we just compute the
    #  homography H from the original image to a perturbed image. In the second branch, we just compute the inv(H)

But I cant find the another branch , have you ever try use two branch and got the worse result?

Now i want to modify the network with two branch, but i dont know how to compute the another pf, if you have ever try the idea,could you please tell me the result you try,if possible can you give me some advise to improve the performance

This comment should have been deleted since it was used for prototype. Basically, it can improve results but it will bring high computational complexity.
