Predicting the Intention to Interact with a Service Robot:the Role of Gaze Cues

no code implementations2 Apr 2024 Simone Arreghini, Gabriele Abbate, Alessandro Giusti, Antonio Paolillo

For a service robot, it is crucial to perceive as early as possible that an approaching person intends to interact: in this case, it can proactively enact friendly behaviors that lead to an improved user experience.

Secure Deep Learning-based Distributed Intelligence on Pocket-sized Drones

no code implementations4 Jul 2023 Elia Cereda, Alessandro Giusti, Daniele Palossi

Palm-sized nano-drones are an appealing class of edge nodes, but their limited computational resources prevent running large deep-learning models onboard.

Deep Neural Network Architecture Search for Accurate Visual Pose Estimation aboard Nano-UAVs

no code implementations3 Mar 2023 Elia Cereda, Luca Crupi, Matteo Risso, Alessio Burrello, Luca Benini, Alessandro Giusti, Daniele Jahier Pagliari, Daniele Palossi

In this work, we leverage a novel neural architecture search (NAS) technique to automatically identify several Pareto-optimal convolutional neural networks (CNNs) for a visual pose estimation task.

Training Lightweight CNNs for Human-Nanodrone Proximity Interaction from Small Datasets using Background Randomization

no code implementations27 Oct 2021 Marco Ferri, Dario Mantegazza, Elia Cereda, Nicky Zimmerman, Luca M. Gambardella, Daniele Palossi, Jérôme Guzzi, Alessandro Giusti

We consider the task of visually estimating the pose of a human from images acquired by a nearby nano-drone; in this context, we propose a data augmentation approach based on synthetic background substitution to learn a lightweight CNN model from a small real-world training set.

Sensing Anomalies as Potential Hazards: Datasets and Benchmarks

1 code implementation27 Oct 2021 Dario Mantegazza, Carlos Redondo, Fran Espada, Luca M. Gambardella, Alessandro Giusti, Jérôme Guzzi

We consider the problem of detecting, in the visual sensing data stream of an autonomous mobile robot, semantic patterns that are unusual (i. e., anomalous) with respect to the robot's previous experience in similar environments.

Semantic Segmentation on Swiss3DCities: A Benchmark Study on Aerial Photogrammetric 3D Pointcloud Dataset

no code implementations23 Dec 2020 Gülcan Can, Dario Mantegazza, Gabriele Abbate, Sébastien Chappuis, Alessandro Giusti

We introduce a new outdoor urban 3D pointcloud dataset, covering a total area of 2. 7 $km^2$, sampled from three Swiss cities with different characteristics.

Learning to predict metal deformations in hot-rolling processes

no code implementations22 Jul 2020 R. Omar Chavez-Garcia, Emian Furger, Samuele Kronauer, Christian Brianza, Marco Scarfò, Luca Diviani, Alessandro Giusti

Hot-rolling is a metal forming process that produces a workpiece with a desired target cross-section from an input workpiece through a sequence of plastic deformations; each deformation is generated by a stand composed of opposing rolls with a specific geometry.

Vision-based Control of a Quadrotor in User Proximity: Mediated vs End-to-End Learning Approaches

1 code implementation24 Sep 2018 Dario Mantegazza, Jérôme Guzzi, Luca M. Gambardella, Alessandro Giusti

We consider the task of controlling a quadrotor to hover in front of a freely moving user, using input data from an onboard camera.

Learning Long-range Perception using Self-Supervision from Short-Range Sensors and Odometry

3 code implementations19 Sep 2018 Mirko Nava, Jerome Guzzi, R. Omar Chavez-Garcia, Luca M. Gambardella, Alessandro Giusti

We introduce a general self-supervised approach to predict the future outputs of a short-range sensor (such as a proximity sensor) given the current outputs of a long-range sensor (such as a camera); we assume that the former is directly related to some piece of information to be perceived (such as the presence of an obstacle in a given position), whereas the latter is information-rich but hard to interpret directly.
