Contextual Detection of Pedestrians and Vehicles in Orthophotography by Fusion of Deep Learning Algorithms

Masoomeh Shireen Ansarnia, Etienne Tisserand, Patrick Schweitzer, Mohamed Amine Zidane, Yves Berviller
2022 Sensors  
The presented results show that the method allows one to detect road users, identify the surfaces on which they move, quantify their apparent velocity, and estimate their actual velocity.  ...  The proposed method in this work focuses on analyzing video streams captured from a vertically installed camera, and performing contextual road user detection.  ...  On the other hand, a more substantial dataset will be necessary to train the network for roads and sidewalks. However, generally, the similarity between these two factors is deceiving for the model.  ...

An effective Time-Aware Map Matching process for low sampling GPS data [article]

Paolo Cintia, Mirco Nanni
2016 arXiv   pre-print
The process of associating a segment of the underlying road network to a GPS point gives us the chance to enrich raw data with the semantic layer provided by the roadmap, with all contextual information  ...  Moreover, our algorithm is parameter-free and does not depend on specific characteristics of the GPS localization error and of the road network (e.g. density of roads, road network topology, etc.).  ...  In [6] a method to get rid of this assumption has been proposed: a gravity model is used to associate a GPS point, with his speed, to a road segment, choosing between the k-nearest neighbor.  ...
