According to the noise and overlapping characteristics of agricultural irrigation water quality monitoring data for the comprehensive evaluation may bring about the boundary fuzzy problem. This paper proposes an improved Genetic Algorithm (GA) to avoid premature convergence, the global optimal solution of the function of the Projection Pursuit (PP) function is used as the comprehensive evaluation...
This letter presents a multi-frame extension of the well-known spectral flux method for unsupervised musical onset detection. Instead of comparing only the spectral content of two frames, the proposed method takes into account a wider temporal context to evaluate the dissimilarity between a given frame and its previous frames. More specifically, the dissimilarity is measured by using the previous...
Saliency prediction is valuable in many video applications, such as intelligent retrieval, advertisement design and delivering, video coding and video summarization generating. Although image saliency is well explored, less works have been done on videos. Compared to images, the semantic orientation is more obvious for video saliency. In this paper, we propose a method to predict video saliency by...
In the conventional rate distortion optimization (RDO) video coding, the measure of distortion is mainly from the perspective of signal processing, while dose not fully take into account the characteristics of visual perception. People have concerns about not only the information of independent pixels, but also the temporal and spatial correlations between them. For different video content, human...
Abstrac---After the share structure split reform, the relationship between Ownership Concentration degree and corporate performance is the focus of the community. In this study, we select 300 Index companies listed in Shanghai and shenzhen stock exchange during 2007-2009 as samples, and use regression models to inspect the the relationship between ownership concentration degree and corporate performance,it...
In order to find the gap between the Chinese team and the other team, we had analysed to the six games of china in the 2010 World Cup qualifier by the method of grey reational analysis. The results showed that some technical indicators had a greater impact on the competition results such as shooting being plugging, shooting, offside, yellow card, the so on. It aimed to discover the rule and characteristics...
