From the outset of automated generation of summaries, the diÆculty of evaluation has been widely discussed (e.g., [10] [25]). Despite many promising attempts, we believe it remains an unsolved problem. Here we present a method for scoring the content of summaries of any length against a weighted inventory of content units, which we refer to as a pyramid. Our method is derived from empirical ana...

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...

This project asks you to study the supplied code for enhancing high resolution medical and scientific images and develop from it a Map-Reduce distributed task that performs the same enhancement – but has the capability to process, in a timely way, images many times the size. The image processing technique uses a Laplacian Pyramid to find and enhance edges in frequency space, and tunes the greys...

The Hough transform is used to detect patterns in images. Its advantage is the ability to detect discontinuous patterns in noisy images. The drawback is its demand for a large amount of computing power. EEcient algorithms and their implementations in multiprocessor systems have been proposed to overcome the computational requirements. The ability to eeciently map two-dimensional (2D) images int...

Text block segmentation is necessary in document layout analysis. An algorithm and its implementation that segregates text block by block (a block is either a title or a paragraph) from the provided document, e.g. newspaper image, based on pyramid structure is described in this paper. The pyramid structure, which is amenable for parallel processing on output, is a multi-resolution image represe...

Automatic information extraction from unstructured sources is known to be a challenging task. It involves a number of sequential stages that transforms initial raw data to the source of knowledge in some field. In this paper we concentrate on the problem of the unsupervised free-text processing and structuring – 1 level of information extraction in the information pyramid we further introduce i...

We discovered a technical solution of such outstanding importance that it can trigger new approaches in silicon wet etching processing and, in particular, photovoltaic cell manufacturing. The so called inverted pyramid arrays, outperforming conventional pyramid textures and black silicon because of their superior light-trapping and structure characteristics, can currently only be achieved using...

Presented is a new 80 GOPS video-processing chip capable of performing video rate vision applications. These applications include real-time video stabilization, mosaicking, video fusion, motion-stereo and video enhancement. The new vision chip, codenamed Acadia, is the result of over 15 years of research and development by Sarnoff in the areas of multi-resolution pyramid-based vision processing...

In this paper an approach for automatic aerotriangulation (AAT) is presented, which is designed for frame and three-line imagery. We will focus on the extraction of conjugate points, because the geometric differences in geometry of frame and three-line imagery can be considered as well-known and are only different modules at the implementation stage. Our approach uses point features and a coars...

This paper presents a practical classification system for recognising diseased wheat leaves and consists of a number of components. Pre-processing is performed to adjust the orientation of the primary leaf in the image using a Fourier Transform. A Wavelet Transform is then applied to partially remove low frequency information or background in the image. Subsequently, the diseased regions of the...
