WebApr 11, 2024 · In addition, each layer of the two paths has a symmetric skip connection, which is more conducive to the fusion of features. To reduce information loss, we choose a convolution with a stride of 2 for down-sampling in encode path [37]. Each decode path includes four layers: up-sampling, convolution, batch-normalization(B.N.) and concatenate.
