We address the problem of populating object category detection datasets with dense , per-object 3D reconstructions , bootstrapped from class labels , ground truth figure-ground segmentations and a small set of keypoint annotations .
 object category detection datasets, per-object 3D reconstructions; ground truth figure-ground segmentations, per-object 3D reconstructions; ground truth figure-ground segmentations, keypoint annotations; keypoint annotations, per-object 3D reconstructions
