Monocular 3D human pose and shape estimation is an ill-posed problem since
multiple 3D solutions can explain a 2D image of a subject. Recent approaches
predict a probability distribution over plausible 3D pose and shape parameters
conditioned on the image. We show that these approaches exhibit a trade-off
between three key properties: (i) accuracy - the likelihood of the ground-truth
3D solution under the predicted distribution, (ii) sample-input consistency -
the extent to which 3D samples from the predicted distribution …
