Most of the models for image segmentation today are the variants of the classical U-Net. By applying some improvements on the convolution blocks and skip connections in U-Net, this paper proposes a ...

U-Net is characterized by its encoder-decoder architecture and pioneering skip ... U-Net++ introduces nested and dense skip connections, further strengthening the connection between the encoder and ...

Decoder: The decoder upsamples the image to restore its original dimensions. It uses information from both the encoder's output and its own previous outputs. Skip Connections: One unique feature of ...

In the new network, only the neighboring high- and low-dimensional feature maps of the encoder ... U-Net uses a symmetric architecture to suppress the key image features by down-sampling and to ...
