I'm sorry for the lack of explanation.
I would like to know the flow from shooting a human with Kinect to outputting the joint position.

CNN = Convolution Neural Network
The CNN returns up to 32 joint locations per detected skeleton.
The (human) Model Fitter combines the CNN output with depth data, information on the human form, and temporal information to compute the final position of all 32 joints in 3D per skeleton. It will estimate joints missed by the CNN. You can use the confidence level to determine if the Model Fitter has estimated a joint position.
