Multi-Task Cross-Modality Deep Learning for Pedestrian Risk Estimation
Participants : Danut Ovidiu Pop, Fawzi Nashashibi.
We want to solve the problem of multi-task pedestrian protection system (PPS) including not only pedestrian classification, detection and tracking,but also pedestrian action-unit classification and prediction, and finally pedestrian risk estimation. The goal of our research work is to develop an intelligent pedestrian protection component based only on single stereo vision system using an optimal cross-modality deep learning architecture in order to fulfill the prior requirements.
The system has to be able not only to detect all the pedestrians with high precision but also to track all the pedestrian paths, to classify the current pedestrian action and to predict their next actions and, finally, to estimate the pedestrian risk by the time to crossing for each pedestrian.
First, we investigate the classification component where we analyzed how learning representations from one modality would enable recognition for other modalitie(s) within various deep learning, which one terms as cross-modality learning. Second, we study how the cross modality learning improves an end-to-end the pedestrian action detection. Third, we analyze the pedestrian action prediction and the estimation of time to cross the street.
This work has been done in collaboration with Alexandrina Rogozan and Abdelaziz Bensrhair of INSA Rouen. More detail can be fund in , , ,  and in the PhD manuscript of Danut Ovidiu Pop .
