Speech articulation assessment using dynamic magnetic resonance imaging techniques
Ventura, Sandra Moreira Rua; Vasconcelos, Maria João; Freitas, Diamantino Rui; Ramos, Isabel Maria; Tavares, João ManuelMagnetic Resonance Imaging (MRI) has been successfully applied on real-time analysis of the articulators during speech production along the whole vocal tract, with good signal-to-noise ratio and without ionizing effects. Because speech dynamic events need a minimal sampling rate, an improvement on the temporal resolution of MRI systems is demanded. Our aim is to describe a dynamic MRI technique to acquire and ...
Modelling and segmentation of the vocal tract during speech production by using...
Vasconcelos, Maria João; Ventura, Sandra Moreira Rua; Freitas, Diamantino Rui; Tavares, João ManuelThe first and second authors would like to thank the support of the PhD grants with references SFRH/BD/28817/2006 and SFRH/PROTEC/49517/2009, respectively, from Fundação para a Ciência e Tecnol ogia (FCT).

Analysis of tongue shape and motion in speech production using statistical mode...
Vasconcelos, Maria João; Ventura, Sandra Moreira Rua; Tavares, João Manuel; Freitas, Diamantino RuiThe mechanisms of speech production are complex and have been raising attention from researchers of both medical and computer vision fields. In the speech production mechanism, the articulator’s study is a complex issue, since they have a high level of freedom along this process, namely the tongue, which instigates a problem in its control and observation. In this work it is automatically characterized the tong...
Computer analysis of objects’ movement in image sequences: methods and applicat...
Tavares, João Manuel R.S.; Carvalho, Fernando; Oliveira, Francisco; Reis, Ilda; Vasconcelos, Maria João M.; Gonçalves, Patrícia; Pinho, Raquel; Ma, ZhenComputer analysis of objects’ movement in image sequences is a very complex problem, considering that it usually involves tasks for automatic detection, matching, tracking, motion analysis and deformation estimation. In spite of its complexity, this computational analysis has a wide range of important applications; for instance, in surveillance systems, clinical analysis of human gait, objects recogn...
O desafio das marcas ou o contínuo desenho da vida
Vasconcelos, Maria JoãoO desafio da operacionalização da identidade concebido a partir do design enquanto disciplina de gestão de marcas. O processo da re(construção) vivido e reflectido através de um caso concreto – a mudança de imagem da GALP ENERGIA. A gestão de marcas como a reinvenção permanente da vida.
