Skip connections in INet

Hello there,

I am trying to implement an Inet and a DenseINet but there are special skip connections mentioned in the original paper from Wang et al. ( 10.1109/ACCESS.2021.3053408 called “CUSTOMIZED RESIDUAL SHORTCUT” and “CONVOLUTIONAL INDEX” shown in the following image. I know how to implement the normal skip function for ResNet but not for this kind of connection in between blocks. Thx for any advice.
