我正在实施一篇关于图像分割的论文。它基于对 u-net 架构的轻微修改。
该论文基于编码器和解码器步骤以下是我无法理解的论文行。

In the decoder path, features from the encoder path at the same 
resolution are fused through concatenation.

然后给出网络的架构——

Layer .  Output size .  Filter Size    Stride Dropout
Inputs .  _ .              _ .           _ .    _

为了简洁起见，我没有添加其他列值。任何想阅读整篇论文的人，就是这个。所需行见表 1。
