The P300 signal is widely used in brain computer interfaces (BCIs) because of its high recognition accuracy, flexible number of commands and short training time. Mapping P300 signals into control commands, namely, P300 signal processing is the research core of BCIs. Focusing on variability of raw data collected from different electrodes, a multi-sensor weighted support vector machine (msw-SVM) algorithm...
In order to overcome the major implementation problem of long delay line requirement in the conventional transmitted reference (TR) signaling, transmitted reference pulse cluster (TRPC) structure was proposed and further developed for noncoherent ultra-wideband (UWB) systems. In this paper, weighted autocorrelation receiver (WAcR) is introduced for the TRPC system with hybrid binary phase shift keying...
In this paper a new method of blind bandwidth extension from wideband (WB) to super-wideband (SWB) audio is proposed. The Radial Basic Function (RBF) neural network is utilized to predict the coefficients of high-frequency (HF) based on the nonlinear characteristics of audio spectrum series. In addition, the linear extrapolation is used for reconstructing the envelop of HF spectrum. The bandwidth...
Video analysis of athlete action is becoming an important tool for sports training, since it has no intervention to the athlete and there are abundant archived data it can exploit. In this paper we present our work on the automatic analysis of complex individual actions in diving video aiming at providing biometric measurements and visual tools for coaching assistant and performance improving. The...
