Adversarial Identity Injection for Semantic Face Image Synthesis

no code implementations16 Apr 2024 Giuseppe Tarollo, Tomaso Fontanini, Claudio Ferrari, Guido Borghi, Andrea Prati

Among all the explored techniques, Semantic Image Synthesis (SIS) methods, whose goal is to generate an image conditioned on a semantic segmentation mask, are the most promising, even though preserving the perceived identity of the input subject is not their main concern.

EmoVOCA: Speech-Driven Emotional 3D Talking Heads

no code implementations19 Mar 2024 Federico Nocentini, Claudio Ferrari, Stefano Berretti

The domain of 3D talking head generation has witnessed significant progress in recent years.

Towards Controllable Face Generation with Semantic Latent Diffusion Models

1 code implementation19 Mar 2024 Alex Ergasti, Claudio Ferrari, Tomaso Fontanini, Massimo Bertozzi, Andrea Prati

To address that, in this paper we propose a SIS framework based on a novel Latent Diffusion Model architecture for human face generation and editing that is both able to reproduce and manipulate a real reference image and generate diversity-driven results.

ScanTalk: 3D Talking Heads from Unregistered Scans

no code implementations16 Mar 2024 Federico Nocentini, Thomas Besnier, Claudio Ferrari, Sylvain Arguillere, Stefano Berretti, Mohamed Daoudi

Speech-driven 3D talking heads generation has emerged as a significant area of interest among researchers, presenting numerous challenges.

Semantic Image Synthesis via Class-Adaptive Cross-Attention

2 code implementations30 Aug 2023 Tomaso Fontanini, Claudio Ferrari, Giuseppe Lisanti, Massimo Bertozzi, Andrea Prati

Thus, they tend to overlook global image statistics, ultimately leading to unconvincing local style editing and causing global inconsistencies such as color or illumination distribution shifts.

Automatic Generation of Semantic Parts for Face Image Synthesis

1 code implementation11 Jul 2023 Tomaso Fontanini, Claudio Ferrari, Massimo Bertozzi, Andrea Prati

Also, we show our model can be put before a SIS generator, opening the way to a fully automatic generation control of both shape and texture.

Generating Multiple 4D Expression Transitions by Learning Face Landmark Trajectories

no code implementations29 Jul 2022 Naima Otberdout, Claudio Ferrari, Mohamed Daoudi, Stefano Berretti, Alberto del Bimbo

We thus propose a new model that generates transitions between different expressions, and synthesizes long and composed 4D expressions.

Complete Verification via Multi-Neuron Relaxation Guided Branch-and-Bound

1 code implementation ICLR 2022 Claudio Ferrari, Mark Niklas Muller, Nikola Jovanovic, Martin Vechev

State-of-the-art neural network verifiers are fundamentally based on one of two paradigms: either encoding the whole verification problem via tight multi-neuron convex relaxations or applying a Branch-and-Bound (BaB) procedure leveraging imprecise but fast bounding methods on a large number of easier subproblems.

Instance-wise algorithm configuration with graph neural networks

1 code implementation10 Feb 2022 Romeo Valentin, Claudio Ferrari, Jérémy Scheurer, Andisheh Amrollahi, Chris Wendler, Max B. Paulus

We pose this task as a supervised learning problem: First, we compile a large dataset of the solver performance for various configurations and all provided MILP instances.

Sparse to Dense Dynamic 3D Facial Expression Generation

no code implementations CVPR 2022 Naima Otberdout, Claudio Ferrari, Mohamed Daoudi, Stefano Berretti, Alberto del Bimbo

This allows us to learn how the motion of a sparse set of landmarks influences the deformation of the overall face surface, independently from the identity.

As additional contribution, we enrich the original dataset by using the annotated landmarks to deform and project the 3DMM onto the images.

Fairness Behind a Veil of Ignorance: A Welfare Analysis for Automated Decision Making

no code implementations NeurIPS 2018 Hoda Heidari, Claudio Ferrari, Krishna P. Gummadi, Andreas Krause

We draw attention to an important, yet largely overlooked aspect of evaluating fairness for automated decision making systems---namely risk and welfare considerations.
