Since neither $P(z|X)$ nor $P(Y|x)$ are known a priori (X: Input image, Y: Output segmentation), they rely on a Conditional Variational Autoencoder (VAE) to learn it. They also show through an interesting figure that the learned latent space does grasp the variability of human annotators. Created by: Danny Woods. which they occur, doing so significantly better than published approaches. They show that in both case, their method is better on average (Fig.4).
