A Counter-Forensic Method for CNN-Based Camera Model Identification

no code implementations6 May 2018 David Güera, Yu Wang, Luca Bondi, Paolo Bestagini, Stefano Tubaro, Edward J. Delp

We examine in this paper the problem of identifying the camera model or type that was used to take an image and that can be spoofed.

Reduced Memory Region Based Deep Convolutional Neural Network Detection

no code implementations8 Sep 2016 Denis Tome', Luca Bondi, Emanuele Plebani, Luca Baroffio, Danilo Pau, Stefano Tubaro

Accurate pedestrian detection has a primary role in automotive safety: for example, by issuing warnings to the driver or acting actively on car's brakes, it helps decreasing the probability of injuries and human fatalities.
