The paper describes on-going work on a system that transforms page-oriented document images into “reflowable document images”, representations of the page image in HTML format that allows it to adapt to display devices of different sizes while preserving the original appearance of the image as much as possible and avoiding OCR errors. The approach to document layout analysis used by the system ...

In this paper we propose an approach for Document Layout Analysis based on local correlation features. We identify and extract illustrations in digitized documents by learning the discriminative patterns of textual and pictorial regions. The proposal has been demonstrated to be effective on historical datasets and to outperform the state-of-the-art in presence of challenging documents with a la...

In this paper, a new algorithm of approximating rational triangular B-B surfaces using polynomial triangular B-B surfaces is presented. This algorithm has a simple expression and insured convergence. The core idea of the algorithm is to yield a polynomial triangular B-B surface, which has the same degree and new control vertices of the degree-elevated rational triangular B-B surface, to approxi...

geographic information systems (gis) are one of the fastest growing computer-based technologies of past two decades, yet, full potential of this technology in construction has not been realized. based upon gis capabilities, construction site layout is one of the areas that gis could be applied. the layout of temporary facilities (tfs) such as warehouses, fabrication shops, maintenance shops, co...

In this study, solutions for machinery layout with the aim of reducing transportation costs will be discussed. To do this, imperialist competitive algorithm (ICA), which is a very complicated and effective meta-heuristic algorithm is introduced. In the offered algorithm, different kinds of machinery layout are considered in single-row as country and then the best possible layout is developed ba...

We describe a feature-rich conditional random field model for the extraction of conference and workshop information (e.g. name, date, location, deadline) from calls for papers (CFPs). This has applications in the automatic construction of a conference knowledge base from a collection of CFPs. Relevant information in CFPs is often contained in regions that do not contain complete, grammatical se...

The comprehensive syntax of iStar modeling language allows requirements analysts to clearly capture stakeholder’s needs, as well as dependencies among stakeholders. However, such iStar models cannot be automatically laid out using typical layout algorithms, such as hierarchical layout and circular layout. Thus, constructing and adjusting iStar models are laborious tasks, especially when dealing...
