Learning Group Activities from Skeletons without Individual Action Labels
Fabio Zappardino, Tiberio Uricchio, Lorenzo Seidenari +1
To understand human behavior we must not just recognize individual actions but model possibly complex group activity and interactions. Hierarchical models obtain the best results i…

Image Retrieval using Multi-scale CNN Features Pooling
Federico Vaccaro, Marco Bertini, Tiberio Uricchio +1
In this paper, we address the problem of image retrieval by learning images representation based on the activations of a Convolutional Neural Network. We present an end-to-end trai…

Localization of JPEG double compression through multi-domain convolutional neural networks
Irene Amerini, Tiberio Uricchio, Lamberto Ballan +1
When an attacker wants to falsify an image, in most of cases she/he will perform a JPEG recompression. Different techniques have been developed based on diverse theoretical assumpt…
