Dimension conflicts in summation operation in bilateral guided aggregation layer

[JianqiangRen]

In Fig 6 of your paper, left input of sum is a tensor with shape of HxWxC, and right input is H/4xW/4xC, how can they be added ? Do you neglect a 4x upsample operation when drawing this figure?

[MikoyChinese]

There is an upsample operation after the feature maps of size (N, C, H/4, W/4).
