The scale invariant property of an ensemble of natural images is examined which motivates a new early visual representation termed the higher order pyramid. The representation is a non-linear generalization of the Laplacian pyramid and is tuned to the type of scale invariance exhibited by natural imagery as opposed to other scale invariant images such as 1/f correlated noise and the step edge. ...

This paper presents a new automated method for evaluating the content of a text summary. The proposed method is based on a combination of features encompassing scores of content and others of linguistic quality. This method relies on a learning technique called linear regression. The objective of this combination is to predict the PYRAMID score from the features used. In order to evaluate the p...

Coxeter decompositions of hyperbolic simplices where studied in math.MG/0212010 and math.MG/0210067. In this paper we use the methods of these works to classify Coxeter decompositions of bounded convex pyramids and triangular prisms in the hyperbolic space IH.

The role of diet quality and physical activity in reducing the progression of chronic disease is becoming increasingly important. Dietary Quality Indices or Indicators (DQIs) are algorithms aiming to evaluate the overall diet and categorize individuals according to the extent to which their eating behaviour is "healthy". Predefined indexes assess dietary patterns based on current nutrition know...

Article history: Received 21 September 2011 Received in revised form 28 December 2012 Accepted 7 January 2013 Available online 23 January 2013 This paper investigates how the state-controlling ownership and the ownership through corporate pyramid structures affect the dividend policies of publicly listed firms in China. We find that the state-controlled firms in China pay higher dividends (meas...

Objective: To find an association between diet and benign prostatic hyperplasia (BPH) and carcinoma prostate (CaP). Methodology: Ninety three out of 250 subjects were selected representing the normals, BPH and CaP cases; food frequency questionnaire was duly filled. Food intake was calculated by using food guide pyramid and was categorized as low, moderate and high. In addition to common diets,...

Untapped markets are often deemed institutional voids, terra incognita ripe with economic possibility. The conversion of voids into viable has become the ambition many corporations today, which view marginal and under-served areas such as urban slums opportunities to achieve dual aims market growth poverty reduction, particularly through ‘bottom pyramid’ (BoP) programmes. This article examines ...

Background: There is a striking lack of evidence about parents’/caregivers’ influence on their children’s dietary intake across Brazil and other middleand low-income countries. Therefore, the purpose of this study was to identify the associations between adolescents’ dietary intake and home environment, family meals and parental support. Methods: Cross-sectional study with 14–18 years old adole...

There is evidence showing a close relationship between diet and the occurrence of non-communicable chronic diseases. The present study assessed food consumption in a 2002/2004 cohort of young adults born in 1978/79 in Ribeirão Preto, SP, Brazil. The composition of the habitual diet consumed by a sample of 2063 individuals aged 23-25 years was analyzed using a validated semi-quantitative food fr...

Foveated imaging exploits the fact that the spatial resolution of the human visual system decreases dramatically away from the point of gaze. Because of this fact, large bandwidth savings are obtained by matching the resolution of the transmitted image to the fall-off in resolution of the human visual system. We have developed a foveated multiresolution pyramid (FMP) video coder/decoder which r...
