Hi @xuuuuuuchen ,
Thanks for your quick reply.
In eq. (11), length term requires to compute the derivative of u
. However, the derivative has been computed by forward difference here.
Active-Contour-Loss/Active-Contour-Loss.py
Lines 14 to 15 in f90dd4a
from active-contour-loss.
The purpose for line 17 & 18 line is to compute within (a-1, a-1) shape, because after line 14 & 15, the shape of x & y are like (a-1, a) and (a, a-1),
Hope it answers your question.

Hi @xuuuuuuchen ,
Thanks for your reply.
I understand, but I think the shape of delta_x/y
is (a-2, a-2) in your code. For ACDC, it is (254, 254).

@JunMa11 Yes, it is (a-2, a-2) not (a-1, a-1) in this code. I'm trying to make sure the shape of delta_x/delta_y
is always square as well as contain meaningful info., but you could try on (a-1, a-1). I think there's no big difference if the image size is large enough.
Hope it answers your question.

Got it. Yes, a-1
or a-2
is not critical.
Thanks for your reply very much.
