Neural network have many architecture. And the architecture of Unet is included encoder and decoder these two part. Unet basic on FCN ( Fully Convolutional Networks ) to using on the encoder. Each level layer will step down the image by convolution filter and collect the feature map. The decoder will reverse the encoder and output to the segmentation.
