Unlike previous approaches, our parts are both selected and trained to improve qualitative pose discrimination and are shared by all the qualitative pose models. ...
We present a discriminative deformable part model for the recovery of qualitative pose, inferring coarse pose labels (e.g., left, frontright, back), a task which we expect to be more robust to common confounding ...

We have shown it is not only possible to estimate 3D poses by applying part detectors used in 2D pose estimation, but that it is also beneficial to the 2D pose estimation itself, as the 2D deformations ...
