Fig. 4: Unconditional generation captures common anatomic variations but fail to capture outliers.
From: Probing the limits and capabilities of diffusion models for the anatomic editing of digital twins
Diagonal plot shows the 2D morphological distribution (shown as a scatterplot) exhibited by real cohorts and synthetic cohorts generated by unconditional sampling from a generative VAE and diffusion model. Marginal plots show the equivalent 1D morphological distributions for the virtual anatomy cohorts, visualized as a kernel density estimate plot.
