It is a challenging issue to analyze video content for video mining tasks due to lacking of effective representation of video. In this paper, we propose a novel key frame representation algorithm based on rough sets (RS) in discrete cosine transform (DCT) compressed-domain. Firstly, we extract DCT coefficients in compressed-domain, select and preprocess the DC coefficients that derived from DCT coefficients...
Most of the speech recognition systems are all based on the technology of HMM because that HMM is a valid probability tool for modeling and recognizing time-series signal and can provide a better statistical architecture. But the weakness such as the poor performance in classification and the high dependence on the statistical knowledge of the pre-experimentation is unconquerable. So we introduce...
High-light grown cells of Thalassiosira pseudonana and Pavlova lutheri constituted a superior diet for larval Pacific oysters (Crassostrea gigas) relative to the same phytoplankton species grown under low-light. Growth rates were higher and mortality was lower for those larvae fed high-light (HL) versus low-light (LL) grown phytoplankton cells of the same species. Based upon larval growth rates,...
