Public ISBD Titre : Artificial intelligence-based system for accident prevention on railways Type de document : document électronique Auteurs : Hanane Hamar, Auteur ; Sarah Si Youcef, Auteur ; Sid-Ahmed Berrani, Directeur de thèse Editeur : [S.l.] : [s.n.] Année de publication : 2020 Importance : 1 fichier PDF (13 M) Présentation : ill. Note générale : Mode d'accès : accès au texte intégral par intranet. Mémoire de Projet de Fin d’Études : Électronique : Alger, École Nationale Polytechnique : 2020 Bibliogr. f. 66 - 70 Langues : Anglais (eng) Mots-clés : Train Railway Computer Vision Machine learning Accident prevention Object Detection Evaluation Distance Estimation Index. décimale : PN00620 Résumé : Railway transport suffers from a major problem which is accidents, where the losses in hu-man lives and the materials are enormous. To solve this problem or at least reduce the number of accidents, railway safety has proposednumerous initiatives with different methods and technologies. In this work, a method usingartificial intelligence is proposed. The system developed must comply with numerous conditions contrary to the systems de-signed for the autonomous vehicle sector. One of the key challenges is long-range obstacledetection. Sensor technology in current land transport research is able to look 200 m ahead. A system that combines two types of cameras; RGB and thermal; is suggested to consider thedifferent requirements. these ones consist of the different illumination and weather conditions,and also the range needed to detect obstacle on time. This work is divided into two parts. The first one is the obstacle detection. To do so,three common object detection algorithms have been evaluated and compared (effectivenessand efficiency comparison). The algorithm with the lowest FAR( false Alarm rate), the bestDR (Detection Rate), and that achieves the shortest execution time has been chosen. Theobjective is to build a reliable system that can operate in real-time.The second part focuses on the estimation of the distance between objects and the train usingthe DisNet algorithm. Here, two evaluation methods have been used in order to assess theprecision of the estimation.

In this thesis, we also investigate the effect of label space size on the OOD detection performance, for that we used three different in-distribution datasets (CIFAR-10, CIFAR-100 and ImageNet-1K), and we showed that the performance degrades rapidly as the number of in-distribution classes increases. We concluded by proposing a method that surpasses the three previous methods in detection performances and by creating a web user interface to test out our OOD detection method.
