direct regression and heatmaps

[weiguochow]

Hi,

1. The first method is coordinate regression method, whether the label is pixel coordinate or world coordinate for the loss calculation.

2. What is the next two line code meaning? Could you give more information in details? Thank you!

norm_xyz_pose = tf.divide(xyz_pose - tf.tile(com,[jnt_num]), POSE_NORM_RATIO) gt_oms = tf.reshape(gt_normed_poses, (-1,1,1,3*self._jnt_num)) - xyzs

Hey,

1. the coordinate regression part is not included in the released code here.
2. oms means offset map, it is used to calculate offset maps.
