Back to the Future: GNN-based NO$_2$ Forecasting via Future Covariates

no code implementations8 Apr 2024 Antonio Giganti, Sara Mandelli, Paolo Bestagini, Umberto Giuriato, Alessandro D'Ausilio, Marco Marcon, Stefano Tubaro

Remarkably, we find that conditioning on future weather information has a greater impact than considering past traffic conditions.

Super-Resolution of BVOC Emission Maps Via Domain Adaptation

1 code implementation22 Jun 2023 Antonio Giganti, Sara Mandelli, Paolo Bestagini, Marco Marcon, Stefano Tubaro

In our work, we aim at super-resolving low resolution emission maps derived from satellite observations by leveraging the information of emission maps obtained through numerical simulations.

Super-Resolution of BVOC Maps by Adapting Deep Learning Methods

no code implementations15 Feb 2023 Antonio Giganti, Sara Mandelli, Paolo Bestagini, Marco Marcon, Stefano Tubaro

Biogenic Volatile Organic Compounds (BVOCs) play a critical role in biosphere-atmosphere interactions, being a key factor in the physical and chemical properties of the atmosphere and climate.

Detecting GAN-generated Images by Orthogonal Training of Multiple CNNs

1 code implementation4 Mar 2022 Sara Mandelli, Nicolò Bonettini, Paolo Bestagini, Stefano Tubaro

For this reason, detecting if an image is an actual photograph or has been synthetically generated is becoming an urgent necessity.

Amplitude SAR Imagery Splicing Localization

no code implementations7 Jan 2022 Edoardo Daniele Cannas, Nicolò Bonettini, Sara Mandelli, Paolo Bestagini, Stefano Tubaro

Synthetic Aperture Radar (SAR) images are a valuable asset for a wide variety of tasks.

Forensic Analysis of Synthetically Generated Western Blot Images

no code implementations16 Dec 2021 Sara Mandelli, Davide Cozzolino, Edoardo D. Cannas, Joao P. Cardenuto, Daniel Moreira, Paolo Bestagini, Walter J. Scheirer, Anderson Rocha, Luisa Verdoliva, Stefano Tubaro, Edward J. Delp

As a matter of fact, the generation of synthetic content is not restricted to multimedia data like videos, photographs or audio sequences, but covers a significantly vast area that can include biological images as well, such as western blot and microscopic images.

DIPPAS: A Deep Image Prior PRNU Anonymization Scheme

1 code implementation7 Dec 2020 Francesco Picetti, Sara Mandelli, Paolo Bestagini, Vincenzo Lipari, Stefano Tubaro

A typical trace exploited for source device identification is the Photo Response Non-Uniformity (PRNU), a noise pattern left by the device on the acquired images.

Training CNNs in Presence of JPEG Compression: Multimedia Forensics vs Computer Vision

no code implementations25 Sep 2020 Sara Mandelli, Nicolò Bonettini, Paolo Bestagini, Stefano Tubaro

In this work, we focus on the effect that JPEG has on CNN training considering different computer vision and forensic image classification problems.

A Modified Fourier-Mellin Approach for Source Device Identification on Stabilized Videos

1 code implementation20 May 2020 Sara Mandelli, Fabrizio Argenti, Paolo Bestagini, Massimo Iuliani, Alessandro Piva, Stefano Tubaro

To decide whether a digital video has been captured by a given device, multimedia forensic tools usually exploit characteristic noise traces left by the camera sensor on the acquired frames.

Video Face Manipulation Detection Through Ensemble of CNNs

2 code implementations16 Apr 2020 Nicolò Bonettini, Edoardo Daniele Cannas, Sara Mandelli, Luca Bondi, Paolo Bestagini, Stefano Tubaro

In this paper, we tackle the problem of face manipulation detection in video sequences targeting modern facial manipulation techniques.

CNN-based fast source device identification

1 code implementation31 Jan 2020 Sara Mandelli, Davide Cozzolino, Paolo Bestagini, Luisa Verdoliva, Stefano Tubaro

Source identification is an important topic in image forensics, since it allows to trace back the origin of an image.

Facing Device Attribution Problem for Stabilized Video Sequences

1 code implementation5 Nov 2018 Sara Mandelli, Paolo Bestagini, Luisa Verdoliva, Stefano Tubaro

Specifically, we propose: (i) a strategy to extract the characteristic fingerprint of a device, starting from either a set of images or stabilized video sequences; (ii) a strategy to match a stabilized video sequence with a given fingerprint in order to solve the device attribution problem.
