In video-fluoroscopic swallowing assessment the time taken for the bolus material to transit the oral and pharyngeal regions is currently estimated by visual inspection. This paper presents an effective method for objectively approximating these timings by fitting a Gaussian surface to the first derivative of the intensity profiles along user defined anatomical boundaries. The profile characteristics...
This paper describes an optimization strategy for steady state visual evoked potential (SSVEP)-based brain-computer interface (BCI), especially in a spelling program application. In this application, there are at least three components for implementing a complete BCI application: stimulator, signal processing, and application (spelling program). Ideally, those three components should run on different...
