Attention allows us to prioritize the processing of external information according our goals, but also cope with sudden, unforeseen events. processes rely on coordinated activity large-scale brain networks. At cortical level, these systems are mainly organized in fronto-parietal networks, functional and anatomical asymmetries favor right hemisphere. Dysfunction right-lateralized networks often ...

Underlying recognition is an organization of ob jects and their parts into classes and hierarchies A rep resentation of parts for recognition requires that they be invariant to rigid transformations robust in the presence of occlusions stable with changes in viewing geometry and be arranged in a hierarchy These constraints are captured in a general framework using notions of a part line and a p...

In this paper, we present a study of visual speech in Arabic. More specifically, we performed a lipreading recognition experiment on Arabic, where a set of consonant-vowel stimuli were presented as visual-only speech and participants were asked to report what they recognized. The overall lipreading scores were consistent with other experiments in other languages. The resulting consonant confusi...
