Implementation of the U-Net decoder. Paper: https://arxiv.org/abs/1505.04597

Parameters:
  • input_channels (List[int]) – The channels of the input features.

  • input_reductions (List[int]) – The reduction factor of the input features.

  • decoder_channels (Optional[List[int]]) – The channels on each layer of the decoder.

  • upsample_layer (Type[Module]) – Layer to use for the upsampling.

  • norm_layer (Type[Module]) – Normalization layer to use.

  • activation_layer (Type[Module]) – Activation function to use.

  • extra_layer (Type[Module]) – Addional layer to use.

  • mismatch_layer (Type[Module]) – Strategy to deal with odd resolutions.

forward(*features)

Forward pass of the decoder.

Parameters:

*features (Tensor) – Features from the encoder, the first is the input image, last one the deepest.

Return type:

Tensor

property out_classes: int

Number of output classes.
