Thanks to the recent advances in deep learning and the availability of big datasets, biometric systems boast of having high performance. However, these systems suffer from two main shortcomings, non-revocability, and vulnerability to biometric spoofing. Due to the GDPR, it has become increasingly important to have tools and methods to protect the privacy of the users. The H2020 SpeechXRays project...Show More
Human-Machine Interaction systems have not yet reached all the emotional and social capacities. In this paper, we propose a face emotion recognition system from static image based on the Xception convolution neural network architecture and the K-fold-cross-validation strategy. The proposed system was improved using the fine-tuning method. The Xception model pre-trained on ImageNet database for obj...Show More
The purpose of this work is to present a solution combining user-friendliness and cost-effectiveness use of audio (speech) & visual (video/image) biometrics, for eHealth, able to achieve better accuracy and increase the ability to avoid counterfeiting. This work shows the evaluation results for an eHealth pilot study that tested the security, privacy, usability and cost-effective features of a use...Show More
We are interested in the reproducibility of face recognition systems. By reproducibility we mean: is the scientific community, and are the researchers from different sides, capable of reproducing the last published results by a big company, that has at its disposal huge computational power and huge proprietary databases? With the constant advancements in GPU computation power and availability of o...Show More
