Hi guys,
I am trying to implement the segmentation network proposed in [1].

I have two questions regarding the interpretation of that diagram:

Following the down convolution, there is always a new cube added in the back. How would you interpret this? I am guessing that it’s the

nfilters * 1                                   nfilters * 1   
   |_ nfilters * 2                       nfilters * 2_|
      |_ nfilters * 3              nfilters * 3_|
          |_ nfilters * 4 | nfilters * 4 _|   


How would I execute the concatenation step? I was thinking about the following:

 |_ nfilters * 3 (left side) ---> compress(squeze to one filter) and concat  --> nfilters * 2 (right side) --> resulting in nfilters * 3


What do you guys think?
Thanks a lot,
Best
Christian
