Questions about Detail Emphasis Module

[Shaw-Way]

Hi, thanks for your remarkable work. I have some questions about Detail Emphasis Module. https://github.com/kamiLight/CADepth-master/blob/8251f12f21393aae3261c3765218063cea1cae30/networks/dem.py#L4-L19 I noticed that it contains 2 parts, the first is conv1, the second is global_path. It seems the second one is similar to Channel Attention Module. But I have no idea what is the function of the first part(conv1). May I ask how you conceived the first part or where it came from? Thanks in advance.
