Query: Recognition and 3D Localization of Pedestrian Actions from Monocular
  Video   Understanding and predicting pedestrian behavior is an important and
challenging area of research for realizing safe and effective navigation
strategies in automated and advanced driver assistance technologies in urban
scenes. This paper focuses on monocular pedestrian action recognition and 3D
localization from an egocentric view for the purpose of predicting intention
and forecasting future trajectory. A challenge in addressing this problem in
urban traffic scenes is attributed to the unpredictable behavior of
pedestrians, whereby actions and intentions are constantly in flux and depend
on the pedestrians pose, their 3D spatial relations, and their interaction with
other agents as well as with the environment. To partially address these
challenges, we consider the importance of pose toward recognition and 3D
localization of pedestrian actions. In particular, we propose an action
recognition framework using a two-stream temporal relation network with inputs
corresponding to the raw RGB image sequence of the tracked pedestrian as well
as the pedestrian pose. The proposed method outperforms methods using a
single-stream temporal relation network based on evaluations using the JAAD
public dataset. The estimated pose and associated body key-points are also used
as input to a network that estimates the 3D location of the pedestrian using a
unique loss function. The evaluation of our 3D localization method on the KITTI
dataset indicates the improvement of the average localization error as compared
to existing state-of-the-art methods. Finally, we conduct qualitative tests of
action recognition and 3D localization on HRI's H3D driving dataset.
