The Pyramid Scheme: Visual Metaphors and the USDA's Pyramid Food Guides

Rebuilding the food pyramid.

The Mediterranean food guide pyramid.

t has been said that the Mediterranean regions have the most healthful dietary traditions in the world, especially when compared to other industrialized countries, like the United States. This statement is supported by epidemiological studies done in the region. In order to improve our own dietary habits it can be beneficial to look at other cultures' cuisine and incorporate some of their habit...

Burt and Adelson : Laplacian Pyramid the Gaussian Pyramid

We describe a technique for image encoding in which local operators of many scales but identical shape serve as the basis functions. The representation differs from established techniques in that the code elements are localized in spatial frequency as well as in space. Pixel-to-pixel correlations are first removed by subtracting a lowpass filtered copy of the image :From the image itself. The r...

Pyramid-based Computer Graphics the Pyramid Representation and Computer Graphics

Pyramid-based graphics techniques can provide realistic computer graphics on small systems without the complexities of physics simulations. Human beings have an intuitive feel for graphics. Graphics problems such as blending two images smoothly, interpolating to fill in missing image data, or creating realistic looking images are routinely solved by artists using traditional media. It i s much ...

Psychosocial Basis of a Sustainable Food Pyramid

Drawing on FAO’s definition of “sustainable diet”, we propose a “sustainable food pyramid” (SFP) which aims to eradicate malnutrition, promote health and protect the environment. These aspirational objectives require changes in the productive system, eating habits of the population, and rebalancing power relations between all actors in the food chain. This study addresses the psychosocial attit...
