Facial Kinship Verification from remote photoplethysmography

no code implementations14 Sep 2023 Xiaoting Wu, Xiaoyi Feng, Constantino Álvarez Casado, Lili Liu, Miguel Bordallo López

Specifically, in this paper, we employed a straightforward one-dimensional Convolutional Neural Network (1DCNN) with a 1DCNN-Attention module and kinship contrastive loss to learn the kin similarity from rPPGs.

Hardening RGB-D Object Recognition Systems against Adversarial Patch Attacks

no code implementations13 Sep 2023 Yang Zheng, Luca Demetrio, Antonio Emanuele Cinà, Xiaoyi Feng, Zhaoqiang Xia, Xiaoyue Jiang, Ambra Demontis, Battista Biggio, Fabio Roli

We empirically show that this defense improves the performances of RGB-D systems against adversarial examples even when they are computed ad-hoc to circumvent this detection mechanism, and that is also more effective than adversarial training.

Non-contact Pain Recognition from Video Sequences with Remote Physiological Measurements Prediction

no code implementations18 May 2021 Ruijing Yang, Ziyu Guan, Zitong Yu, Xiaoyi Feng, Jinye Peng, Guoying Zhao

The framework is able to capture both local and long-range dependencies via the proposed attention mechanism for the learned appearance representations, which are further enriched by temporally attended physiological cues (remote photoplethysmography, rPPG) that are recovered from videos in the auxiliary task.

Are spoofs from latent fingerprints a real threat for the best state-of-art liveness detectors?

no code implementations7 Jul 2020 Roberto Casula, Giulia Orrù, Daniele Angioni, Xiaoyi Feng, Gian Luca Marcialis, Fabio Roli

We investigated the threat level of realistic attacks using latent fingerprints against sensors equipped with state-of-art liveness detectors and fingerprint verification systems which integrate such liveness algorithms.

Revealing the Invisible with Model and Data Shrinking for Composite-database Micro-expression Recognition

no code implementations17 Jun 2020 Zhaoqiang Xia, Wei Peng, Huai-Qian Khor, Xiaoyi Feng, Guoying Zhao

In this paper, we analyze the influence of learning complexity, including the input complexity and model complexity, and discover that the lower-resolution input data and shallower-architecture model are helpful to ease the degradation of deep models in composite-database task.

Deep Neural Rejection against Adversarial Examples

1 code implementation1 Oct 2019 Angelo Sotgiu, Ambra Demontis, Marco Melis, Battista Biggio, Giorgio Fumera, Xiaoyi Feng, Fabio Roli

Despite the impressive performances reported by deep neural networks in different application domains, they remain largely vulnerable to adversarial examples, i. e., input samples that are carefully perturbed to cause misclassification at test time.

Local feature hierarchy for face recognition across pose and illumination

no code implementations12 Jul 2016 Xiaoyue Jiang, Dong Zhang, Xiaoyi Feng

Accordingly we propose an end-to-end face recognition method to deal with pose and illumination simultaneously based on convolutional networks where the discriminative nonlinear features that are invariant to pose and illumination are extracted.
