To evaluate the perceived realism of our results, we com-
pare ICON to PIFu∗, PaMIR∗, and the original PIFuHD [55]
in a perceptual study. ICON, PIFu∗ and PaMIR∗ are trained
on all 3, 709 scans of AGORA [47] and THuman [71] (“8x”
setting in Fig. 6). For PIFuHD we use its pre-trained model.
In the study, participants were shown an image and either a
rendered result of ICON or of another method. Participants
were asked to choose the result that best represents the shape
of the human in the image. We report the percentage of trails
in which participants preferred the baseline methods over
ICON in Tab. 3; p-values correspond to the null-hypothesis
that two methods perform equally well. For details on the
study, example stimuli, catch trials, etc. see Appx
