A Global Convolutional Network, or GCN, is a semantic segmentation building block that utilizes a large kernel to help perform classification and localization tasks simultaneously. It can be used in a FCN-like structure, where the GCN is used to generate semantic score maps. Instead of directly using larger kernels or global convolution, the GCN module employs a combination of 1×k+k×11 \times k + k \times 1 and k×1+1×kk \times 1 + 1 \times k convolutions, which enables dense connections within a large k×kk\times{k} region in the feature map
