Figure 6.

Figure presenting a comparison between synthesized MRIs generated by a VAE and a Hamiltonian VAE [159]. Both models were trained on a limited training set of 100 images from BraTS2020 Challenge dataset. The first row showcases original images, while the second and third rows present synthesized images generated by the VAE and Hamiltonian VAE, respectively. While the images generated by both models appear slightly fuzzy, the Hamiltonian VAE demonstrates enhanced performance in generating realistic images. This comparison highlights the robustness of the VAE and Hamiltonian VAE for generating new images from a small dataset [158].
