Automatic speech analysis is currently evolving towards hybrid systems that combine both visual and acoustic information. This is due to limitations of existing acoustic-based approaches and the need for robust speech recognition systems working under extremely challenging conditions including noisy environments. We introduce in this paper a novel visual(More)
Bioenergy crops are expected to provide biomass as a replacement for fossil resources, but their impact on the water cycle is still under question. This study aimed at both quantifying the ability of bioenergy crops to use soil water and analysing the relationship between their root systems and soil water uptake. Water content was monitored continuously for(More)
It is admitted that human speech perception is a multimodal process that combines both visual and acoustic informations. In automatic speech perception, visual analysis is also crucial as it provides a complementary information in order to enhance the performances of audio systems especially in highly noisy environments. In this paper, we propose a unified(More)
