Questions about eq(3), eq (8) and eq(12) in the paper

[emjay73]

I have some questions about the equations in the paper.
I think those equations should be corrected.
If I misunderstood something, please let me know.

(3)
in the paper

(8) Parenthesis position is somewhat weird.

(12) Scale factor defined in MPI and MINE is in a reverse relationship, but equations do not reflect the difference.

Eq. 3

d_i = 1 / z_i. z_n is the nearest plane depth with smallest value, while z_f is the farthest plane depth with the largest value. Therefore, d_n > d_f. In Eq. 3, (d_f - d_n) < 0. So the equation is correct.

Eq. 8

You are correct, there is a redundent left parentheses on Z_src(x,y). Thanks for pointing it out. We will update our arxiv paper.

Eq. 12

You are correct, the predicted disparity D_src / D_tgt should be multiplied by scale s.

Thanks a lot for pointing out the errors in the paper.

Oh yeah, about eq 3, I confused near/far notation with z, not disparity.
Thanks! Things get clear for me.
