To improve the performance of a top-hat transformation for infrared small target enhancement, a new class of top-hat transformation through structuring element construction and operation reorganization is proposed. The structuring element construction and operation reorganization are based on the property of the infrared small target image and thus can greatly improve the performance of small t...

In this paper we provide an analytical description of various classes of digital circles, spheres and in some cases hyperspheres, defined in a morphological framework. The topological properties of these objects, especially the separation of the digital space, are discussed according to the shape of the structuring element. The proposed framework is generic enough so that it encompasses most of...

Using the terms of (Reiter and Dale, 2000), we consider that the Document Planner architecture is pipelined: first the content determination task does its work, and then the document structuring task takes the result and build a document plan. Following the work of (Roussarie, 2000), we adopt SDRT (Asher, 1993; Asher and Lascarides, 1998), which was designed first for text understanding, for th...

In this paper a decomposition technique suitable for any grey-scale soft morphological structuring element is presented. A hardware structure implementing this technique is also presented.

• Compose personalized documents for the reader. For example, once could have a text base on statistical methods, where each topic is treated at several levels (such as for readers who know calculus and those who do not) and where each method has examples from several domains. Given a reader’s background, subject domain, and learning goal, the system would then sequence of topics that build on ...

The present study set out to delineate to what extentfive intermediate learners engaged in structuring and problematizing scaffolding in two writing tasks. The study aimed at illuminating how the participants engaged with structuring and problematizing scaffolds cognitively, behaviorally, and affectively.  Learners’ written essays, think-aloud protocols, and interviews shaped the data sources w...

The decomposition of a binary morphological structuring element is a well-known problem that has often been addresses in the literature. This work present a new approach based on an Evolution Program: using an iterative stochastic technique,it allows to determinethe optimal decomposition of an arbitrarily shaped binary morphological structuring element into the shortest chain of elementary fact...

A number of different algorithms have been described in the literature for the decomposition of both convex binary morphological structuring elements and a specific subset of nonconvex ones. Nevertheless, up to now no deterministic solutions have been found to the problem of decomposing arbitrarily shaped structuring elements. This work presents a new stochastic approach based on Genetic Algori...
