Question about paper. about gscnn

[tovacinni]

Thanks for your interest in our work!

1. Yes, I believe Eq.(6) is missing a minus sign. We will fix this, thanks for pointing it out!

2. We use canny edges.

3. We use bilinear upsampling.

2/3. We plan on releasing the code soon, so hopefully these questions would be answered more accurately once that happens.

Hi, When can i get the code for this project?

[arc144]

Thanks for your paper and reply. May I also ask some questions?

1. How do you use the ASPP module to fuse the regular stream with shape stream? Do you apply ASPP only to regular stream, upsample it and then concatenate with shape stream followed by 1x1 conv?

2. In the shape stream figure there is a conv1x1 leading to another conv1x1 (from gradients) does it mean that you concat the results of both convolutions?

3. Finally, if I'm working in a binary context (foreground/background) may I simply replace the CE-losses for BCE and replace the argmax/gumbel softmax with a simple treshold?

Thanks a lot. Will the code be released this month?

1/2. We have released the code now so I think the code would better answer that question.

3. I believe so! We have tried our network with some private datasets in a binary context and results do seem to improve. Thresholding is one strategy, but you could also consider having 2 classes (foreground / background).

The code has been released.
