Opposite sign of Z value #28

Hi, I found the Z value of joints(showed in joints.txt) in MSRA dataset are negative. But the depth image pixels values are all positive, and when transformed to 3D, their Z values(which are pixel values) stay unchanged in current code. So they have opposite signs on Z and cannot match in 3D space. Did I miss something?

PS. I also tried to correct the sign of Z of ground truth joints, and they can match well.

Thanks!
