The determination algorithm of neighbor video cameras by deployed position and view distance of video camera is introduced in this paper. This algorithm is utilized to determine the neighbor video cameras in the automatic human tracking system. The automatic human tracking system is enhanced video monitoring system utilizing the mobile agent technologies. Information of the neighbor video cameras...
We propose an approach to modeling Chinese tonal patterns, focusing on the basic fundamental frequency (F0) patterns characterized by the contextual linguistic features that can be directly extracted from text. We analyze tonal patterns as sparse target points (tonal F0 peaks and valleys) and represent them in parametric form within the framework of a functional F0 model. The relationships between...
Chinese is a tonal language. It has both lexical tones and intonation. The fundamental frequency (F0) contours thereby consist of tone and intonation components. This paper presents an approach to modeling the two components in separate ways and combining them to form the final F0 contours based on a functional F0 model. We analyze tonal patterns as sparse target points (tonal F0 peaks and valleys)...
In this paper, we proposed a robust speech feature extraction algorithm for automatic speech recognition which reduced the noise effect in the temporal modulation domain. The proposed algorithm has two steps to deal with the time series of cepstral coefficients. The first step adopted a modulation contrast normalization to normalize the temporal modulation contrast of both clean and noisy speech to...
