Query: Pedestrian Path, Pose and Intention Prediction through Gaussian Process
  Dynamical Models and Pedestrian Activity Recognition   According to several reports published by worldwide organisations, thousands
of pedestrians die in road accidents every year. Due to this fact, vehicular
technologies have been evolving with the intent of reducing these fatalities.
This evolution has not finished yet since, for instance, the predictions of
pedestrian paths could improve the current Automatic Emergency Braking Systems
(AEBS). For this reason, this paper proposes a method to predict future
pedestrian paths, poses and intentions up to 1s in advance. This method is
based on Balanced Gaussian Process Dynamical Models (B-GPDMs), which reduce the
3D time-related information extracted from keypoints or joints placed along
pedestrian bodies into low-dimensional spaces. The B-GPDM is also capable of
inferring future latent positions and reconstruct their associated
observations. However, learning a generic model for all kind of pedestrian
activities normally provides less ccurate predictions. For this reason, the
proposed method obtains multiple models of four types of activity, i.e.
walking, stopping, starting and standing, and selects the most similar model to
estimate future pedestrian states. This method detects starting activities
125ms after the gait initiation with an accuracy of 80% and recognises stopping
intentions 58.33ms before the event with an accuracy of 70%. Concerning the
path prediction, the mean error for stopping activities at a Time-To-Event
(TTE) of 1s is 238.01mm and, for starting actions, the mean error at a TTE of
0s is 331.93mm.
