Traditional video coding and streaming algorithms do not been fully utilized in content information of video in bit allocation and adaptation. This paper proposes a content-based video streaming method based on visual attention model to better utilize network bandwidth and achieve better subjective video quality. First, visual attention model is exploited(More)
Recently the research on supervised term weighting has attracted growing attention in the field of Traditional Text Categorization (TTC) and Sentiment Analysis (SA). Despite their impressive achievements, we show that existing methods more or less suffer from the problem of over-weighting. Overlooked by prior studies, over-weighting is a new concept(More)
Developers often wonder how to implement a certain functionality (e.g., how to parse XML files) using APIs. Obtaining an API usage sequence based on an API-related natural language query is very helpful in this regard. Given a query, existing approaches utilize information retrieval models to search for matching API sequences. These approaches treat queries(More)
Trimethylamine (TMA) N-oxide (TMAO), a gut-microbiota-dependent metabolite, both enhances atherosclerosis in animal models and is associated with cardiovascular risks in clinical studies. Here, we investigate the impact of targeted inhibition of the first step in TMAO generation, commensal microbial TMA production, on diet-induced atherosclerosis. A(More)
Web content structure is proposed to facilitate automatic web page adaptation in this paper. By identifying the logic relationship of web content based on layout information, web content structure effectively represents au-thors' presentation intention. An automatic top-down, tag-tree independent approach to detect web content structure is presented. It(More)
This paper introduces an approach for image shadow removal by using pulse coupled neural network (PCNN), based on the phenomena of synchronous pulse bursts in the animal visual cortexes. Two shadow-removing criteria are proposed. These two criteria decide how to choose the optimal parameter (the linking strength /spl beta/). The computer simulation results(More)
