Improvement of emotion recognition from facial images using deep learning and early stopping cross validation

Mohamed Bentoumi, Mohamed Daoud, Mohamed Benaouali, Abdelmalik Taleb-Ahmed

Inthis paper, we present a new approach for emotion recognition from facial images. The proposed method is based on the association of a pretrained convolutional neural network (CNN) model (VGG16, ResNet50) with a multilayer perceptron (MLP) classifier. The pretrained CNN model is used as a feature...

Nano drone bioinspiré à ailes vibrantes

Marguerite de la Bigne, Mathieu R Colin, Sofiane Ghenna, Eric Cattan, Grondel Sébastien, Olivier Thomas

Cet exposé montre les derniers travaux sur le dimensionnement d’un nanodrone bio-inspiré à ailes vibrantes. Cette étude s’intègre à un projet qui a pour objectif de faire décoller le plus petit drone au monde. Son originalité réside dans les techniques de fabrication utilisées, puisque le drone est...

On the influence of water on THz vibrational spectral features of molecular crystals

Sergey Mitryukovskiy, Danny Vanpoucke, Theo Hannotte, Melanie Lavancier, D. Hourlier-Bahloul, Goedele Roos, Romain Peretti

The collective vibrations in molecular crystals can be probed using terahertz spectroscopy, providing unique characteristic spectral fingerprints. However, the association of the spectral features to the crystal conformation, crystal phase and its environment is a difficult task. We present a...

Complex refractive index determination of PTFE, TPX and polypropylene windows for TeraHertz broadband spectroscopy

J. Bichon, A. Pillet, A. Sklia, D. Petitprez, Romain Peretti, S. Eliet

We perform TeraHertz characterization of three low-loss polymer candidates, i.e. polytetrafluoroethylene, polymethylpentene, and polypropylene, to choose the material with the proper opto-mechanical properties for aerosol and gas broadband spectroscopy cell windows. Samples are analyzed with the...

THz gain measurements in optically pumped ammonia

Alexandra Khabbaz, Guillaume Ducournau, Gaël Mouret, Jean-Francois Lampin

We present experimental results about terahertz gain measurements in ammonia gas optically pumped by a quantum cascade laser. The gain was measured with the help of a vector network analyzer (VNA) and reached 17 dB/m at 1.07 THz.

Noise analysis, noise reduction and covariance estimation for Time domain Spectroscopy

Elsa Denakpo, Theo Hannotte, Melanie Lavancier, Sophie Eliet, Romain Peretti

Time domain spectroscopy is now 30 year old and spread more and more along many fields of analytical sciences. The specificity of this technique reads in its name: measurements are not done in the frequency domain using a dispersive element, but in the time domain. One of the consequences is that...
