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.
