TrainSim: A Railway Simulation Framework for LiDAR and Camera Dataset Generation

no code implementations28 Feb 2023 Gianluca D'Amico, Mauro Marinoni, Federico Nesti, Giulio Rossolini, Giorgio Buttazzo, Salvatore Sabina, Gianluigi Lauro

The railway industry is searching for new ways to automate a number of complex train functions, such as object detection, track discrimination, and accurate train positioning, which require the artificial perception of the railway environment through different types of sensors, including cameras, LiDARs, wheel encoders, and inertial measurement units.

Detecting Adversarial Examples by Input Transformations, Defense Perturbations, and Voting

no code implementations27 Jan 2021 Federico Nesti, Alessandro Biondi, Giorgio Buttazzo

This paper extensively explores the detection of adversarial examples via image transformations and proposes a novel methodology, called \textit{defense perturbation}, to detect robust adversarial examples with the same input transformations the adversarial examples are robust to.
