Estimating 3D trajectories from 2D projections via disjunctive factored four-way conditional restricted Boltzmann machines

作者:

Highlights:

• Estimation of 3D trajectories from their 2D projections given by one camera source.

• Disjunctive factored four way conditional restricted Boltzmann machine (DFFW-CRBM).

• DFFW-CRBMs perform estimation, recognition, and future prediction of 3D trajectories.

• DFFW-CRBMs perform well while require limited amount of labeled data.

• Experiments on complex ball trajectories and human activities.
