This paper presents a novel image representation, which incorporates the principles of Laplacian Pyramid into the irregular graph pyramid. The drawback of the regular Laplacian Pyramid is their lack to keep the topological structure of the image, due to the contraction process in building the Gaussian Pyramid. Irregular graph pyramid is able to hierarchically represent the topological structure...

We present a new supervised framework that learns to estimate automatic Pyramid scores and uses them for optimizationbased extractive multi-document summarization. For learning automatic Pyramid scores, we developed a method for automatic training data generation which is based on a genetic algorithm using automatic Pyramid as the fitness function. Our experimental evaluation shows that our new...

The pyramid network is a hierarchy structure based on meshes. Chen et al. in 2004 proposed a new hierarchy structure, called the enhanced pyramid network, by replacing each mesh at layer greater than one of the pyramid network with a torus. This investigation demonstrates that the enhanced pyramid network with two faulty edges is Hamiltonian. The result is optimal because both edge connectivity...

A given (overcomplete) discrete oriented pyramid may be converted into a steerable pyramid by interpolation. We present a technique for deriving the optimal interpolation functions (otherwise called steering coefficients). The proposed scheme is demonstrated on a computationally efficient oriented pyramid, which is a variation on the Burt and Adelson pyramid. We apply the generated steerable py...

Pyramid annotation makes it possible to evaluate quantitatively and qualitatively the content of machine-generated (or human) summaries. Evaluation methods must prove themselves against the same measuring stick – evaluation – as other research methods. First, a formal assessment of pyramid data from the 2003 Document Understanding Conference (DUC) is presented; this addresses whether the form o...

This study was conducted to determine the prevalence of household food insecurity and its potential risk factors and outcomes among the Orang Asli (Temuan) households. Socioeconomic, demographic and food security information of the households and anthropometric measurements and dietary intakes of preschoolers (n = 64) were obtained using a structured questionnaire. Food security was assessed us...

Dietary guidelines are important tool for selection a healthy diet. There is no special dietary guidelines for Arab people. Health Institutes are mainly using the Western dietary guidelines, such as American Food Pyramid. The objective of this paper therefore, was to summarize the steps taken by Arab Centers for Nutrition to establish "Food Dome", the dietary guidelines for the Arab countries. ...

This paper examines the relationship between capital structure and the inner structure of pyramid in an emerging market economy country. The author uses firm-level panel data of Chinese listed companies to analyze the influence of the inner structure of pyramid on capital structure and the differences between different institutional environments of that influence deeply. His results show that t...
