The below video contrasts interpolations between real images for our model and Glow. The aliasing-artifacts of Glow are clearly visible around the midpoint of the interpolation. Our model also exhibits slightly less pixel-level crossfading between images (e.g. the shoulders in the fourth column).
The final video below complements the standard-deviation visualization of Figure 3 in the paper. Each image is generated by encoding the same image and the replacing a single layer of the latent with a sample from the prior. The samples in both models are untruncated to clearly illustrate the variance, but often result in broken images.
