On the limits of perceptual quality measures for enhanced underwater images

no code implementations12 Jul 2022 Chau Yi Li, Andrea Cavallaro

The appearance of objects in underwater images is degraded by the selective attenuation of light, which reduces contrast and causes a colour cast.

On the reversibility of adversarial attacks

no code implementations1 Jun 2022 Chau Yi Li, Ricardo Sánchez-Matilla, Ali Shahin Shamsabadi, Riccardo Mazzon, Andrea Cavallaro

We refer to this property as the reversibility of an adversarial attack, and quantify reversibility as the accuracy in retrieving the original class or the true class of an adversarial example.

Training privacy-preserving video analytics pipelines by suppressing features that reveal information about private attributes

1 code implementation5 Mar 2022 Chau Yi Li, Andrea Cavallaro

However, the features extracted by a deep neural network that was trained to predict a specific, consensual attribute (e. g. emotion) may also encode and thus reveal information about private, protected attributes (e. g. age or gender).

Underwater image filtering: methods, datasets and evaluation

no code implementations22 Dec 2020 Chau Yi Li, Riccardo Mazzon, Andrea Cavallaro

The growing interest in underwater image filtering methods--including learning-based approaches used for both restoration and enhancement--and the associated challenges call for a comprehensive review of the state of the art.

Exploiting vulnerabilities of deep neural networks for privacy protection

1 code implementation19 Jul 2020 Ricardo Sanchez-Matilla, Chau Yi Li, Ali Shahin Shamsabadi, Riccardo Mazzon, Andrea Cavallaro

To address these limitations, we present an adversarial attack {that is} specifically designed to protect visual content against { unseen} classifiers and known defenses.
