A Structure-Aware Adversarial Framework with the Keypoint Biorientation Field for Multiperson Pose Estimation

Figure 1

(a) Incorrect postures may be generated by ordinary adversarial networks without contact information between joint points. (b) Combining the connection information between local joints and the prior body structure results in more accurate predictions. (c) Keypoint Biorientation Field (KBOF) corresponds to the contact information between two joints. (d) A pair of bidirectional vectors in each pixel of every KBOF encodes the orientation and position information between two keypoints.
