The Pyramid system associates importance ratings with individual sentences in evaluated summaries. Given that many summarization systems compose their output from source document sentences with limited or no editing, it is often possible to propagate Pyramid ratings back to the source document and tag source sentences with one measure of their suitability to a generic summary. In the case of Py...

A pyramid approach for multimodality image registration based on mutual information is presented. The image pyramid is obtained by using the wavelet transform. An exhaustive search algorithm at the coarsest level of the image pyramid is developed. Image partitioning and gray level intensity binning are used to increase the fidelity of the process. Because of the fact that image partitioning is ...

This paper describes indexing of ontological data to reduce the memory consumption of a Rete-based reasoner whose time performance is increased using a hybrid optimization heuristic. The aforementioned indexing mechanism is known as the Pyramid Technique. Our work organizes three dimensional ontological data in a way that works efficiently with this indexing mechanism and it constructs a subset...

Successful instruction of a complicated subject as Physical Rehabilitation demands organization. To understand principles and processes of such a field demands a hierarchy of steps to achieve the intended outcome. This paper is intended to be an introduction to a proposed pyramid scheme of general physical rehabilitation principles. The purpose of the pyramid scheme is to allow for a greater un...

Scene recognition is a basic task towards image understanding. Spatial Pyramid Matching (SPM) has been shown to be an efficient solution for spatial context modeling. In this paper, we introduce an alternative approach, Orientational Pyramid Matching (OPM), for orientational context modeling. Our approach is motivated by the observation that the 3D orientations of objects are a crucial factor t...

An extraordinary light harvesting property of a periodic nano-pyramid array is reported. It is found that the nano-pyramid array can absorb light efficiently with an average absorptivity of 0.998 over the whole visible waveband. The ultra-high absorption is independent of the incoming light on polarization state and insensitive within a broad angle range. We attribute the efficient light harves...

The pyramid networks are well-known as suitable structures for parallel computations such as image processing. This paper shows a practical 3D VLSI layout of the N -vertex pyramid network with volume O(N) and wire-length O( 3 √ N). Since the known best lower bounds for the volume and wire-length of a 3D layout for an N -vertex pyramid network are Ω(N) and Ω( 3 √ N/ log N), respectively, the vol...

Adult cats were trained to use a forelimb to open a hinged door against resistance for a food reward. Normal cats performed the task with only toe or wrist motions. Cats with unilateral complete bulbar pyramid section showed persistent deficits in distal limb movements with toe fanning, wrist stiffness and pulling from elbow and shoulder. Partial medial or lateral pyramid lesions produced simil...

The 3D pyramid compressor project at the University of Glasgow has developed a compressor for images obtained from CLSM device. The proposed method using a combination of image pyramid coder and vector quantization techniques has good performance at compressing confocal volume image data. An experiment was conducted on several kinds of CLSM data using the presented compressor compared to other ...

Image fusion is an important visualization technique of integrating coherent spatial and temporal information into a compact form. Laplacian fusion is a process that combines regions of images from different sources into a single fused image based on a salience selection rule for each region. In this paper, we proposed an algorithmic approach using a Laplacian and Gaussian pyramid to better loc...
