In the view of massive content explosion in World Wide Web through diverse sources, it has become mandatory to have content filtering tools. The filtering of contents of the web pages holds greater significance in cases of access by minor-age people. The traditional web page blocking systems goes by the Boolean methodology of either displaying the full page or blocking it completely. With the i...

The evaluation of web pages against a query is the pivot around which the Information Retrieval domain revolves around. The context sensitive, semantic evaluation of web pages is a non-trivial problem which needs to be addressed immediately. This research work proposes a model to evaluate the web pages by cumulating the segment scores which are computed by multidimensional evaluation methodolog...

Information Extraction has become an important task for discovering useful knowledge or information from the Web. A crawler system, which gathers the information from the Web, is one of the fundamental necessities of Information Extraction. A search engine uses a crawler to crawl and index web pages. Search engine takes into account only the informative content for indexing. In addition to info...

The use of dynamic instruction architectures based on eld-programmable gate arrays (FPGAs) is described. Using this approach, an application speciic instruction based system has been designed for image segmentation which is an important stage in a computer vision system. The speciic application of interest here is texture-based page layout segmentation for document images. The complete segmenta...

Abstract Despite an extensive market segmentation literature, applied academic studies which bridge segmentation theory and practice remain a priority for ...

Character segmentation is a critical preprocessing step for text recognition. In this paper a method is presented that utilizes visual inter-word constraints available in a text image to split word images into smaller image pieces. This method is applicable to machine-printed texts in which the same spacing is always used between identical pairs of characters. The visual inter-word constraints ...

There is an ever increasing number of publications which do not have the “traditional” layout where printed regions are rectangular. Text paragraphs and areas of graphic type may be of any shape, individually rotated and in any arrangement. Previous document analysis techniques are not well suited to such complex layouts. This paper introduces a new method for the segmentation of images of docu...
