This paper presents a novel framework to encode a combinatorial pyramid. A combinatorial pyramid is a hierarchy of successively reduced combinatorial maps. Important properties of the combinatorial pyramids such as topology preservation, the process global and local features within the same data structure, etc. made them useful for image processing and pattern recognition tasks. Their advantage...

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, 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. The t...

For an interconnection network, calculating average distance of it is in general more difficult than determining its diameter. Diameters of pyramid networks are well known. This study calculates average distances of pyramid networks.

OBJECTIVE To present a simplified classification of the deviated nose and the associated treatment outcome. DESIGN Retrospective analysis. SETTING Tertiary care rhinology clinic. PATIENTS Seventy-five individuals (49 males and 26 females) who underwent rhinoplasty for a deviated nose with minimum follow-up of 36 months. MAIN OUTCOME MEASURES Depending on the orientation of 2 horizontal ...

This research seeks to examine the determinants of affiliation to pyramid structure of Malaysian public listed firms. A motivation of the research comes from the phenomenon of pyramid structure causing divergence of ultimate owners' actual ownership and control leading to severe expropriation of minority shareholders' interest. The method adapts Attig Model and employs Panel Generalised Least S...

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 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 ...

Support for economic resource allocation in Application Layer Networks (such as Grids) is critical to allow applications and users to effectively exploit computational and data infrastructure as a utility. The evaluation of resource allocation strategies plays a major part in the selection of a resource allocation method. This paper presents an evaluation framework for resource allocation metho...
