The European Position Paper on Rhinosinusitis and Nasal Polyps 2012 is the update of similar evidence based position papers published in 2005 and 2007. The document contains chapters on definitions and classification, we now also proposed definitions for difficult to treat rhinosinusitis, control of disease and better definitions for rhinosinusitis in(More)
The multi-modal nature of speech is often ignored in human-computer interaction but lip deformation, and other body such as head and arm motion all convey additional information. We integrate speech cues from many sources and this improves intelligibility, especially when the acoustic signal is degraded. This paper shows how this additional, often(More)

Important visual information often disappears when color documents are viewed by color blind people. The algorithm introduced here maps colors using the World Wide Web Consortium evaluation criteria so that detail is preserved for color blind viewers, especially dichromats. The algorithm has four parts: 1) select a representative set of colors from the(More)
In speech recognition, the problem of speaker variability has been well studied. Common approaches to dealing with it include normalising for a speaker’s vocal tract length and learning a linear transform that moves the speaker-independent models closer to to a new speaker. In pure lip-reading (no audio) the problem has been less well studied. Results are(More)
OBJECT The authors describe the utility of and outcomes after endoscopic transnasal craniotomy and skull reconstruction in the management of skull base pathologies. METHODS The authors conducted a observational study of patients undergoing totally endoscopic, transnasal, transdural surgery. The patients included in the study underwent treatment over a(More)
For automatic lipreading, there are many competing methods for feature extraction. Often, because of the complexity of the task these methods are tested on only quite restricted datasets, such as the letters of the alphabet or digits, and from only a few speakers. In this paper we compare some of the leading methods for lip feature extraction and compare(More)
This paper compares three methods of lipreading for visual and audio-visual speech recognition. Lip shape information is obtained using an Active Shape Model (ASM) lip tracker but is not as effective as modelling the combined shape and enclosed greylevel surface using an Active Appearance Model (AAM). A nontracked alternative is a nonlinear transform of the(More)
Colour texture classification has been an area of intensive research activity. From the very onset, approaches to combining colour and texture have been the subject of much discussion, and, in particular, whether they should be considered joint or separately. In this paper we present a comprehensive comparison of the most prominent approaches both from a(More)
